The e8500 is great for gaming, I use the Q6600(have at 3.0GHz). For ram I use 2x2GB PC2 8500 1066MHz and it runs like a champ. My graphics card is a bit better then yours though I have a 4870 1GB. For the 8800GT, 1920x1080p is gonna be sluggish on the highest settings, but it should be playable at least.
