These are going to be the new parts:
--GPU: ASUS EAH6850 DC/2DIS/1GD5/V2 Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity
--CPU: Intel Core i3-2120 Sandy Bridge 3.3GHz LGA 1155 65W Dual-Core Desktop Processor Intel HD Graphics 2000 BX80623I32120
I haven't picked out a PSU because I'm not sure how many watts that GPU requires; any suggestions? Your help is greatly appreciated.
Also, will it be worth the $100 to upgrade from XP to Windows 7? Or will these parts function fine with the former?
