Changed the case to the Rosewill LINE-M to save $50 and changed the MSI HAWK 7870 to the MSI R7950 Twin Frozr for $320

So can I max games now if I overclock the GPU and will that case have enough cooling to keep my rig from getting to hot and will it fit the graphics card?

I'll go for the Gigabyte 7950 since I can get it for $300! My friend also gave me his Corsair TX750 V2 so I'll just use that instead of buying a new psu so that will save me $68. Should I get the Silverstone TJ08-E instead of the Rosewill LINE-M? I want my computer to have good airflow.
