How to improve

There's quite a bit you could do

What you would benefit most from is a new processor. Luckily you've got an LGA775 motherboard which means that it will support Core2 processors. Your motherboard will support 1st generation Core2 Duo processors (but not Core2 Quad or second generation Core2 processors. If you can get your hands on a cheap Core2 Duo E6700 that will be a large improvement even if it is 5 years out of date by now

ok thanks, ill have a look for one on ebay tonight. also right now i have 4 gbs of ram in the motherboard but when i hit properties on my computer its only registering 2 gbs but on pc wizard it also says 4 gbs. im slightly confused by this

That's what happens when you have a 32 bit version of Windows installed. Each virtual memory address space is limited to 4GB and this includes hardware reserved addresses. Your graphics card and other devices reserve some of the addresses and this bumps out the DRAM that would otherwise occupy those locations.

I have a similar old build, but with a Corsair 400w. I'm getting a 6670 this week and I hope I can play some games with the P4 with a little overclock ;p

so i would have to use a 64 bit version of windows to get the full use of the 4 gigs?

how much is the 6670?

32 bit versions of Windows are limited to 4GB virtual address space which means that each application can only address that much including kernel memory. The physical address space is not limited thanks to PAE (however it is limited to 4GB for marketing reasons, server versions of Windows do not have this same limitation) but the hardware will still need to reserve a small amount. In your case it seems to be a little bit over a gigbyte which is unusually high for some reason. So yes, the simple solution is to just install the 64 bit version of Windows

I guess Pinhedd said everything I had to say. Good luck with it!
