id really appreciate any advice cuz im planning on buying this stuff tomorrow

also if anyone fancies talking on msn so i can brain strom them please im me you msn and ill promise not to bug you

thanks alot guys i hope someone helps

You will need a 64bit OS to use all the available ram. You might want to look at AMD cards (the 4850 is sweet)--With that badass PSU, you might want to upgrade to a Crossfire/SLI motherboard for more upgrade options down the road. You will be better off going with a 2x2GB ram configuration for OC Stability (at lower timings).

You may have to repace your HSF if you want to hit 3ghz (every chip is different). You would be able to run the 7200 with cheaper DDR2 800 memory to svae a few bones.
