overclock the Intel C2Q and with the GTX460 (you should get the on sale GTX470 or GTX570) you will be able to game until you're ready for new build.
RAM 4GB(2X2GB) in dual channel mode is fine.
Ya i can OC C2Q to 3Ghz with this board
just need to hold till 2 yrs and then a new gaming rig. May be i can get a better CPU cooler(corsait H50) after few months then i can OC even further .
