Need a GFX Card & A PSU (Urgent, Buying Tomorrow)

[tkin]

nvidia is down at the moment....plus look at the goddamn prices they should be sued for that a 660ti cost's 19+ whereas the next card would be way off that 19+ margin.....compute performance is pathetic considering my gtx 680 is giving me problems already so much so that i am buying a 7950 probably....you wont believe the stuttering...i'll put up a video shortly......................GCN owns it at the moment sad but true

GTX660Ti is the only nVidia card positioned correctly atm.

Elaborate about GTX680 stuttering, and how it has anything to do with its compute performance, a video would help.

im working on it

the softwares i work on are developed in our very own department....it utilizes cpu + gpu + ram.......somehow the gtx680 is causing stuttering....its just plain out lag....you rotate on object(3d) and it refreshes automatically it happens all the time........i put in a friends quadro 400 and it was smooth like butter....then put in a 7950 and it was butter.........

though i get great fps while playing games better than a 7970 at stock but i did seek some work performance out of it considering i paid 40+ for i....its a shame i should have gone for two 7950's in the first place

Actually GCN performs better because AMD has used a lots of CPU based Thread Scheduling technologies in the GCN design. GCN can use X86 Memory handling and for that programmers can easily assign multiple threads to it efficiently using existing X86 Memory optimization techniques unlike some special memory management techniques required for normal GPU programming. because of these assignment, each of the 4 SIMD units inside a single COMPUTE ENGINE can be assigned with 10 threads containing 64 work items each. They can also work in out of order thread execution mode, i.e., when one thread is stalled for unavailability of resources, rather than waiting for the resources to become available, the SIMD unit can fetch any other thread out of the 10 thread assigned to it. Because of these optimization techniques, the execution path of a program in GCN design is very much optimized.

getting a 7950 real soon mate.....i'll seriously advise people not to buy a high end gtx card expecting good performance in gpu intensive works....gamers have no worries though....the 680 has 8-10 fps more than the 7950 in stock in everything full...

GTX680 has almost no compute power, its nvidia's plan to reduce power consumption and heat for gamers, as the entire G6xx line up is aimed at gamers only, for compute 7950/7970 has no equal atm(also this causes the massive power draw and heat like GTX4xx), well maybe the GTX480 would give it a fight, it had massive compute powers as well, but GTX5xx lost some of it and GTX6xx nearly all of it.

Man , it seems kepler cards are really pathetic in general purpose workloads. You should have been more careful in selecting gpu for your kind of work.
Op should get GCN here. Probably you can provide him more insight into this as you both work on similar things.

GTX680 has almost no compute power, its nvidia's plan to reduce power consumption and heat for gamers, as the entire G6xx line up is aimed at gamers only, for compute 7950/7970 has no equal atm(also this causes the massive power draw and heat like GTX4xx), well maybe the GTX480 would give it a fight, it had massive compute powers as well, but GTX5xx lost some of it and GTX6xx nearly all of it.

Yup that's true. Compute will be back again though and it will really bring it this time. Have a look at the following:

Report: Nvidia GK110 Titan GPU to be Available Next Month

Its launching next month with a hefty price tag of $899. But its nearly as powerful as a 690.
The block diagram confirms it having the "double precision" units responsible for compute performance which GK104 lacked.

This is the big kepler. They still have the tdp around 225 watt which is a great thing.
The vram is a massive 6gb gddr5 with a 384bit bus.

There's also this one: Gigabyte NVIDIA GeForce GTX 660 2 GB GDDR5 GV-N660OC-2GD Graphics Card - Gigabyte: Flipkart.com

you should not recommend gfx card from this manufacturer at-least - not for my experience but read this

Guys thanks for the discussion....I bought the Corsair GS 600 PSU....Waited for the GPU as I wasn't sure of the GTX 650. But I am pretty sure I'll buy this- ZOTAC GTX560TI (FERMI) 1GB GDDR5 .Reviews and benchmarks show that the 560 Ti is better than the 650 Ti. What do you guys think ?

560Ti is wayyy more powerful than 650, there's no competition, get 560Ti if you can: AnandTech - Bench - GPU12

PS: Our forum member ithehappy may be selling his 560Ti as he's getting my 580, you could PM him for a quote: *www.thinkdigit.com/forum/members/99398.html

Benchmark Results: Batman: Arkham City : Nvidia GeForce GTX 650 And 660 Review: Kepler At $110 And $230

Here you may see performance of GTX 650 compared to others....
But I recommend HD7770 against GTX 650
HD 7850 against GTX 660

 

[topgear]

for Op's choice GTX 660 is better suited but comparing the gpu computing performance HD7850 is recommended and both are neck to neck when it comes to gaming performance ( may be GTX 660 has some slight advantage ) upto HD resolution

Thanks Tkin...I am not going for AMD cards as I have a fair amount of 3d work to do and I've always had problems with AMD cards & 3D softwares...btw, which series of Nvidia cards is better- The 500 or 600 ? The GTX 560 is also available within my price range.

You see- 3D rendering using 3ds Max or Maya is entirely CPU & RAM dependent. It has nothing to do with GFX cards. But a gfx card is necessary for the display of objects in a 3d viewport. I don't know if you'll believe me but AMD (ATI) cards have always caused my max/ maya viewport objects to lag...When I rotate/ pan or zoom into an object, I get really slow performance & low frame rates...Nvidia has no such problems. Besides Nvidia has two plugins for Photoshop & 3ds Max that I use.

This time you'll face more problems with nVidia. Your information is from the HD 4000 and GTX 200 series era. Outdated.

Better buy GTX 260/280 if you want to do 3D Work. Viewports in 3ds max and Maya are going to be faster in GTX 260/280. GTX 5xx is crippled through drivers and most probably GTX 6xx is also crippled.

Read post #21 here - Polycount Forum - View Single Post - Slow viewports In Maya with new nvidia card ! HD 6950 being (40 fps) 10x faster than GTX 560 Ti (4 fps).

Slow viewports In Maya with new nvidia card ! - Page 2 - Polycount Forum

Once a guy with GTX 480 SLI came to my IRC channel wondering why his Viewport performance is very slow.

[H]ard|Forum - View Single Post - Desktop versus Workstation GPU's? GTX 470 being only 50% of 8800 GTX.

hehe, this guy says Viewports in GTX 470 are even slower than a HD 4670M. (laptop)

I said that already, the entire nVidia 4xx,5xx and 6xx line up has its viewport crippled via drivers and compute diminished to nothing in hardware, maybe Titan will change that, but AMD is the way to go for designers now, period.
