OK, I want to do some experiment on GPU computing on a rig which has the following spec:

i5-2400 CPU @ 3.10GHz
Intel® Desktop Board DH67BL [link: specifications]
4GB DDR3 RAM
Corsair VX450 PSU

Budget: No idea / Flexible

Your suggestions would be highly appreciated.

I saw all monitors from Dell India website, none are having resolution of more than 1080p.
So I want to know whats the point of discussing or evaluating the frame rate at resolutions of 2560 x 1600 or above for various games? It is not enough to look at the fps benchmark at 1080p for various games to decide the GPU for our requriements?

well with the advent of 4k people want to breach the 1080p benchmark. Many tests now a days are done on multi monitor setups. The highend cards are just too quick and the difference between them is too less in lower resolutions.

7850...eyes closed...or increase a bit and get 7870

Well, I was googling, but I am lost in the sea of information. Could you please guide me to a proper 'basic knowledge' of graphics card, with respect to computation. I am not interested in gaming at all.

Also, GROMACS GPU needs CUDA support.

^^ If you can elaborate on what do you want to use the gpu for, then only we can help. So please tell that what will that graphic card be used for ?

The graphics card will be used for running LAMMPS and GROMACS for molecular dynamics(MD) simulation. This would be an experiment on our desktops. If successful, we would be upgrading our CPU-based HPC to include GPUs.

OpenCL would have been better, as far as I understand. The research oriented developments are moving towards OpenCL, but as of now, GROMACS do not support OpenCL. It supports CUDA only. As an addition, we have a lot of work to do in VMD as well (though its importance is secondary to the MD simulations). VMD also works on CUDA (but as I said, VMD is not the deal breaker).

Can anyone tell please how to change the setting of ATI CC so I can get better image quality.
In game image showing kinda bigger pixel not smooth edge.
There are some setting at Nvidia setting to make image quality better(Performance to Quality) but could not find similar at ATI CC.
My bro got 9600GT and me HD5670.
My brother in game pic far more smooth than mine.
HD5670 in game pic looks like more pixelated than 9600GT(with same game graphics settings).
There must be way way to make better image quality for my ATI card.
may be I don't know. :(

So,no one have any idea ?
Need to find best in game image setting for ATI CC.
 

Yep saw that too....wish i could buy it....:cry:
i have a low quality 450w psu from frontech....i am in no position to spend money to buy a new psu....so i opted hd6570 as it consumes low power and thought my psu will handle it....

but was confused b/w the cards i mentioned above...as 6570 has more steam processors than 5670...but 5670 has got a better clock speed ?:confused:
so what matters more when it comes to performance clock speed or no. of steam processors ?

also searched for 512mb 5670 ddr5 version...but didnt find one...that would have been ideal for my budget...:(

I don't think 5670 will be a problem as it doesn't require additional power connector.

thanks for the quick replies...:)
ok i will try to extend my budget....
but which one would you choose b/w the cards i previously mentioned...?

and any online sites where i can find the 512mb ddr5 version of 5670? googled it but didn't find one....
