Minor upgrade or build a new?

[BenHoliday]

My pc is primarily used for gaming but has a second boot partition to handle all my media tasks. Currently I'm trying to keep the price range below $600 as after that I might as well just start building a new rig. I usually buy my stuff off of Newegg or similiar US sites and I'm not a fanboy whatever does the job and handles it well is good to me. My current build from 2 or 3 years back is this:

ABIT AT8 32X 939 ATI CrossFire Radeon Xpress 3200 ATX AMD Motherboard
AMD Athlon 64 4000+ San Diego 2.4GHz Socket 939 Single-Core Processor
OCZ GameXStream OCZ600GXSSLI ATX12V 600W Power Supply
(3x) Seagate Barracuda 7200.10 320GB 7200 RPM SATA 3.0Gb/s Hard Drive
(4x) Crucial Ballistix 512MB 184-Pin DDR SDRAM DDR 400 (PC 3200)
ATI Radeon X1950PRO 256MB 256-bit GDDR3 PCI Express x16

What I would like to do is upgrade the video to an:

XFX GeForce 8800GT Extreme 512MB 256-bit GDDR3 PCI Express 2.0

Then upgrade the memory to:

(3x) Kingston HyperX 1GB 184-Pin DDR SDRAM DDR 400 (PC 3200)

My main concern is will my processor be able to push the 8800GT and will my psu be able to handle the power draw. I would like to be able to hang on to my system a little bit longer until the Intel quad cores drop a little lower in price or AMD delivers one that works but if this is just a pipe dream I can easily just build a new system after minimal arm twisting another month or two down the road.

I wouldn't upgrade the ram, it's really expensive, and it will become useless for your next build. You COULD replace the videocard, since it's PCI-E anyways, and you can throw it in your new rig in a few months. Problem is, you've got a single core CPU. I think I would hold of, since you do allready have 2gb of ram, and a 1950pro, which isn't that crappy at all. On the other hand, for 600$ you can easily buy a 90$ mobo, a 190$ cpu, and 2x2gb of ram.

http://www.newegg.com/Product/...x?Item=N82E16820231122 ram, you can buy 2x2gb for 68$ if you want to go cheap.
http://www.newegg.com/Product/...E16819115037&Tpk=e8400 E8400, can be had for 190$ if you shop around.
http://www.newegg.com/Product/...2E16813128059&Tpk=ds3l 90$ mobo, you can get the abit ip35-e for 80$, cheapest decent mobo to be had.

That's 378$-410$. You can skimp on the CPU, and overclock a cheap one, http://www.newegg.com/Product/...x?Item=N82E16819116036 when overclocked to 3ghz it will be much faster then your current CPU. The E8400 kicks ass though. And I reckon you can squeeze in a 230$ 8800GT 512mb, and you won't be much over 600$ total.

Don't have time to explain ATM but it's not worth it.
DDR1 ram is waste of money.

By time you'll buy quad newer vid cards will be out.

edit: DSF nailed it :thumbsup:

Thanks guys that puts the final nail in that coffin. I will be reviewing your selections I like that mobo as I have no plans for dual video cards it has nice spacing between the PCI-E and pci cards. My current is a bit tight so that is a huge plus always nice to have more then one usable pci slot.
