So I just upgraded my gpu to a msi r9270x 4gb as I was on a budget , I use my pc for gaming only. I'm now thinking of getting another in 3 months time to crossfire , just wondering if this would be a good move ? Or should I just keep the 1 card and save for a few years and update my rig as the rest oft components are nearly 4 years old ? My specs are intel i7 930 @ 4ghz 6gb ram (3x2gb) 750w psu
