So heres my situation, the pc i have now is a generic p.o.s. so im looking to do a complete overhaul to be able to run bf3 on max settings. So im gonna go with an i7 quad core, 8gigs of ram and a top of the line graphics card. I know a 580gtx is the best currently, but to save a few bucks i was thinking of going with a cheaper card for now to hold me over, and then buy whatevers out in november. Is this a good strategy? If so, whats a good placeholder card for around $150 to get me good performance for the next 8 months or so?
