My work is getting rid of a buch of pc's, i can take what i want except the cases, So far i have a supermicro motherboard (p4 775 socket 800mhz) ddr2 ram 512x4 and a 250 gb hdd, I will be able to get a p4 3.13 ghz processor along with power supply, heatsink, dvd drive and cables in the near future, If i puild a franken pc with a p4 3.13 ghz processor and 2 gig of ram and then buy an aftermarket geforce video card(say 8600). will that be suffecient to play source engine games( hl2, dod, cs2, tf2)? I dont plan for it to be full spec or anything but can i get by ok?

Thanks

Need more info to be sure--
Motherboard model ?
so we can be sure that RAM will fit/work
you should be able to play a lot of games-- exactly what is tough to call.
2 gigs of RAM + 3.1 Ghz P4 is fairly respectable.

the mother board is a supermicro P4SCT+2 and I have 4 ram cards that are 512mb and fit into the motherboard but whether or not it will function is the question. The motherboard has 3 PCI X x16 ports and 1 VGA Pro port ans 2 pci ports.

Got any extra harddrives? I'm in desperate need of some but can't afford anything >.>

If they fit the slots-- they should work.
That board has almost the same Chipset as my Asus -- yours is Intel 875
mine is 865PE--Here's the manual:
Supermicro, Inc. | Support | Resources
The latest BIOS update is from June of 2006
I scanned through some of the online FAQ's-- they seem to offer good tech-support.
I don't think it will be a killer gaming system by todays standards... but it will do for many things-- the thing is VGA video will never approach PCI express's performannce

so what will be a good little video card to get that will be optimal for this motherboard? I new from the start it wont be a strong pc but for free(more or less) you cant beat it. I have an acer 5050 laptop with amd turion 1.8ghz x64, 1gig ram, and a ati radeon xpress 1100 integrated video card and this system wont even think about playing any source games so i can only play the older games, I can bearly run fable so anything is better than what i got now.

AGP cards are on their last legs--the interface is "over".... but there's still some decent deals
I'd get one with at least 256 MB Video ram
