Hello. Im looking to upgrade my current system that is really out of date for gaming. Mobo Asus p5g41t-m lx CPU Intel dual core e5700 @ 3ghz 4gb ram (2x2 gb) ddr3 1333Mhz Ati HD 5450 1GB some generic 450W PSU ( I am upgrading this first asap) I want something that can play in high/ultra settings games like Bf3, Crysis, AC sagas, Metro 2033/Last Light, Total war sagas, Tomb Raider, among others I will be using a max resolution of 1360x768 for those games, and I have a $220 budget for video card + PSU. I am highly considering a Radeon 7850 1GB version + a proper power supply but I need more suggestions. Also how much bottleneck will I get if I put that card with my current dual core? Thanks!
