For a budget of $800...you will spend $250 of that on the intel chip. If you went with the AMD FX8350, steamroller will be available on current motherboards. You could spend $180 on the FX8350 which leaves you an extra $70 laying around for a GPU. That money would go a lot further...and I do mean
alot further spent on the GPU. $70 is the difference between a HD 7850 and a HD 7870XT (Tahiti based). Most games are GPU bound, so you would be far better off spending more money there.

See, to get comparable pricing, it will cost you a tier lower GPU. Not that the HD 7850 is bad...but the HD 7870XT is like a HD 7930 OC edition (if such a card existed).
