I am building a new pc for myself soon and will have some money left over (around £500) and have decided to build a pc using windows XP for my slightly older games (silent hunter 3, IL-2 1946 ect.) that only work on windows XP,I have the cpu, cpu cooler, motherboard, RAM, case and hard drive but I don't know what GPU I should buy, on the steam page it says that on IL-2 1946 can use Geforce 2/3/4/fx/6 family cards and silent hunter 3 can only use Geforce 2/3/4/fx family cards so basically I wanna know can I use a 6800 GT with silent hunter 3?
