Did ddr3 ram exist with that mobo....i really dont think so!!!
If you are getting a core 2 duo next week, then look for deals on a 9800 gt...
That card is unbelievably powerful for a 17 -19 inch screen and is still capable of blowing the doors of the latest video games like bf 3, crysis 2, sleeping dogs, alan wake, bulletstorm, bioshock infinite......etc..etc...(not crysis 3 sadly)
but a 9800 gt costs around 100 us dollars...but still i'd say that look for deals...
U can play anything and everything(on high ultra with acceptable frame rates) with a 9800 GT paired with a decent core 2 duo(like e7400 @ 2.8gHZ) , 4 gigs of ram...
But if you dont have a decent 400 watt PSU(antec, corsair,etc), then you have no choice because a 9800 gt is extremely power hungry for its performance....!!
and in that case, just wait and collect more money.....
Best of luck
