How much of a performance increase should I recieve (in a gaming perspective) from my computer, to the one I am going to be building over the next few weeks.
-AMD athlon xp 2600+ (oc to 2800+)

-eVGA Geforce 6800 128mb (AGP 8x)

-GIGABYTE GA-K8NSC-939 Socket 939 NVIDIA nForce3 250Gb ATX AMD Motherboard
-CORSAIR ValueSelect 1GB 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200)
-eVGA Geforce 6800 128mb (AGP 8x) <kept from last PC
-80 gig 7200rpm HD <kept from last pc
-20 gig 7200rpm HD <one i dug up from the computer i had before the one i have now
Also, I burnt out my last power supply (400 watt) fooling around w/ a powered computer (big mistake). Anyway, i replaced my good PSU with the one that came with the case I bought (350 watt, but im not sure if it really is). So my question is, will i be able to run the new parts i am buying w/ my old power supply, or will i have to by a new PSU like the one listed below?
