Does HD 7750 require less power than HD 6670?

yes those are short time tests only but things can change with prolonged use and if @ Op - you do upgrde in the future the PSU will be good though it depends on the componenets you are going to upgrade and if you want to play safe get a Seasonic SS-600BT Eco around 3.8k.

So what you say about Seasonic S12II 430W PSU? Would be more efficient than these Corsair and Antec one?



Intel Pentium Dual Core E2140 @ 1.6Ghz
PCCHIPS P17G board
SAMSUNG HD161HJ HDD SATA
WDC WD5000AADS-00S9B0 HDD SATA
2*1GB Ram
Philips DVD Writer)
5 LED fans + some LED strips along the case (still to install)
MSI R7750-PMD1GD5/OC GPU (planned to purchase)

LOL your processor will bottleneck the card a big time. I have the same processor and same card and the performance of HD 7750 when paired with Intel e2140 is almost same as a 9500gt(Which I had earlier) paired with Intel e2140.

I'm upgrading my processor to FX 6300 in this week or the next week. But seriously if you're not considering to upgrade your processor anytime soon, then I would not suggest you to get HD 7750..because it will be bottle necked a big time. I earlier had a 9500gt and when I upgraded to HD 7750 the fps difference was about 5-6 fps barely on any game over 9500gt.

don't know what was the issue but people have used better card than 9500GT with a e2140 and they got more than 5-6 FPS ;-)

I think you did not get my point? I guess.
"I upgraded to HD 7750 from 9500gt and difference in performance was very less. HD 7750 performed about 5-6 fps (at most) more at every game. Which was certainly "very" less according to my expectation.

You didn't get him actually did you ??

He wants to say that the poor proccy performance made it impossible to get any great performance advantage from better GFX

I got your point but I've seen people getting better performance [ beyond 5-6 fps ] when they upgraded from 9500GT to HD5750/5770 like cards with a e2140 cpu but I do agree with you that performance will be bottlenecked by the low cpu speed unless Oced.

@ prateek - did you get the gpu yet ?

Hmm I was getting about 20 fps at fifa 12 with 9500gt card when I played it with HD 7750 fps was like 25-27 at medium settings 720p.
Gta 4 was about same was getting 17fps with medium on 9500gt (0 shadows/vsync off) got 19fps-20(Nothing more than that) with HD 7750 same settings. MY CPU was never OC'd was at stock 1.6.

I am on GT 9400 + Q8300 [Intel core to qaud] so if I upgrade to 7770 will it bottleneck my CPU ?
And GTA4 runs ok on medium setting with GT9400 on my sigi

no, actually it will unleash the power of your cpu more ;) HD7770 is a big upgrade compared to 9400GT so if you are planning to get one just get one without much hesitation but if you worried about the PSu of yours get a new good one or get HD7750 which also performs very well compared to 9400GT.
