Well its that time again to rebuild my computer in preping for the release of Vanguard. I know I am going to have to go to a 64 bit processor but it has been a while since I have built my system so I had a few questions. Whats the difference in the processer slots I am seeing a few differenet pin slot numbers? Which is the best for gaming and which is the best for future upgrades? I am looking to keep it under $325 for the motherboard and CPU as a unit? I have found some good deals but I wanted to see what others thought. Video card, I want to spend around $150 and was wonder whats a good deal out there for gaming? I have a ATX case atm but it only has a 350 wt power supply, is it better to just buy a new case with say a 420 power supply or buying a new power supply and installing it into the old case? Thanks.
