first i see a gt 220 at 49$ a good card that is faster than A 4650 i see.
next i see a 5550 at 69$ these are comparable to 8800gt speeds.
the gt 240 at 69$ which is already at 9600gt levels. wow
and there we have it, the 9800gt at 69$ surpassing my 9600gt.
granted your not gonna have these cards stretching crysis across 3 screens, but at low res 20" screens theyre great.
Buying older tech has always been a good way of getting better FPS but it does come at the cost of the more advanced features.
The difference these days is that games have stagnated to the point where for a budget gamer it makes no difference really.
You don't need the latest cards from either company to comfortably play any game today at reasonable settings. We don't all need every setting on high
You also don't actually need DDR3 either. My latest Rig is an AM2+ board because i can reuse my DDR2 and save £100. I don't loose much performance and the whole thing is a lot cheaper. I also thanks to the above points about GPU's don't feel the need to get a new GPU for this build.
All of which means better MoBo,PSU,Case and Cooler. All in im getting a new PC for half the cost of the last one and it will be quite a bit faster as well.
I havent seen anything concrete yet but everything im hearing is that the Bulldozer Arch will probably need a new Mobo (socket) and only support DDR3. The latest 6 core chip will run in my AM2+ board so its not like im not 100% up to date chip wise anyway.
