Hey guys, I'm on a $300 budget. I'm waiting for ArmA 2 to come out, and I currently play Flight Simulator X. Now, I am planning to upgrade. I currently own the AMD Athlon X2 6400+ at 3.2GHz. And the eVGA 8800GT 512MB. I need to know whether or not, I should just upgrade the CPU to this: http://www.newegg.ca/Product/Product.aspx?Item=N82E16819103471 OR Get a new Graphics card? Which will give me better performance? Thanks!
