Windows 7: GPU Question

GPU Question

Hi, I got a P7P55D MB and I would like to buy a new graphic card or it's for my brother and I am not quite sure what to do, his budget is about 1700 SEK ( Swedish Currency ) I was thinking 2x 7750 2GB since they are cheaper then some other cards, but that card is a 3.0 PCIe while the MB he got uses 2.0 but most 2.0 GPU's are quite thin when it comes to shop having them in stock. And since there are litteraly a million different GPU's I' quite clueless what would be the best performance for money.

Any help or some explanation would be greatly appreciated

Edit 1: Forgot that he uses a Corsair 650 Modular PSU

PCI-E 3 cards are backwards compatible with PCI-E 2.x motherboards. Don't worry about that.

I think that a single Radeon HD 7850 card would outperform two 7750s in Crossfire, for about the same price. The single card would have the advantage of not using Crossfire.

(Tried that a few years ago with a couple of 4870s. I found the drivers to be problematic then. Maybe they're better now.)

Ye that they are backwards compatible I know of it just seems a bit waste to me since he wont get full bandwidth but I guess that don't really matter, and never used AMD cards before so I'm a bit worried about that too with the whole crossfire thing. But I will look up the 7850.

You, nor him will se any difference between PCIE 2.0 or 3.0.
None. Zero. Null. Nada.

So I guess we will go with a single 7850 then since they got a deal on that one and you get 2x games with it. Thanks for all the help

You won't regret it.

All that I've read suggests that no current graphics card can saturate a PCI-E X16 2.0 slot.

One review site managed to show a small loss in performance with a pair of 7970s used for GPU computing, but software that would expose that is never seen by most people. The effect was modest, anyway.
