temp system to run Doom3/HL2?

[Bruck]

My current machine is no match for Doom 3. p3-600mhz 512mb of ram.

But I may have the following components at my disposal.

P4 1.7ghz , Asus motherboard (not sure of model)

re-usable parts in my current system:

10k rpm scsi 20gb drive
120gb wd 8mb cache ide drive
sb audigy 1 card
ethernet card


Do I "borrow" the 1.7ghz processor and mobo that are not being used by my brother, slap a top of the line video card in it X800 and a good amount of ram, throw it into an antec sonata case with a scsi card?

I am looking to play doom 3 / hl2 very smoothly but I am not sure i want to drop enough cash for a new system right now. I don't use surround sound for gaming, will most likely use my 2 channel harmon kardon's. So i dont think i need a new soundcard.

Would this system be capable for these games? or do I need a faster cpu ?

I'm trying to end up with an almost top of the line system without spending the cash or forefitting the option of BTX in the coming year or 2.

Thanks

You're in for a total re-build.

Three things to think about.

1. CPU/Motherboard
2. Video Card
3. RAM

What I meant is, the cpu/mobo are a perfect match he was using them until he got his new laptop

Is 1.7ghz P4 enough to play Doom 3 well? (given I use a top of the line video card and enough ram)

If you slap a decent video card and 512 ram in there, you should be able to eak by with the minimum system req's, but if that board is a rambus board, don't waste the $$, just get yourself a budget a64 rig.

Ok, It's a P4T board, does not support AGP 8x. Looks like i guess a new system build is in order
