if you have at least 2gb and a mid grade cpu, you wont notice much of a performance decrease... and id rather have good performance AND better visuals (dx10 + any system costing over 600 bucks)Lilgunney612

Well Vista and good performance don't mix. After turning off all the frills in Vista my 3dMark only dropped 800 points from 14.5K when I attempted to switch my system, it's vista ready and solid equiptment but the game play in my 2 main games BF 2142 and DDO were significatnly laggy and the actual Frame Rates in game dropped by HALF and the damned thing kept crasing. Just enough te effect the gameplay in Titan mode on 2142 and the Orchard in DDO.

Just my 2 cents but Vista is Horrid for Gaming. It sure is georgus I just wish it worked.
