So I have a XFX 7750 2 gb ddr3 and want to add a second identical card. The only problem is I know my 700 psu can handle it, and I know my board has 2 PCI x16 slots. The concern comes into the second pci x16 slot, it says it runs in X4 mode which, I assume, mean that the crossfire wont offer the performance boost I am looking for. Can someone tell me what kind of boost I would get in games like Starcraft 2 where im getting 30-35 max fps on ultra settings? Would it even be worth the 130 upgrade to add a second card or wait to get a larger card later. As only being in High school I am always on a budget here.

The 2nd PCi-E X16 slot on that motherboard support x4 bandwidth only, meaning the crossfire performance on that motherboard will be beyond terrible, with 2 cards running at pci-e x4 bandwidth. It's best to get a stronger card instead. Plus, some games including Starcraft 2 don't support dual VGA setups well, so there's a big chance that you'll get a FPS drop instead of increase for running 2 HD7770.

My cpu currently is only running at 3.6 GHz mainly due to the jet turbine levels coming from my stock cooler. I am currently working on getting a new cooler before I OC as im running up to 60C with the stock cooler at 6-6.5k rpm. Once I get a new cooler I am planning to OC.

As for a newer card, I am looking for a card that wont break the bank, but will still last me a long time. I bought this gpu for an old computer and thats why its ddr3. Obviously I cant afford a 7990 but something like the 7950 might be good. I tend to lean to AMD.
