I am looking to upgrade one of my PC's for light gaming but need some help or suggestions.
I have:
PC chips M848A:rev2.1 motherboard
AMD Duron 1.2GHz
ATI radeon 9200se video card
Maxtor DiamondMax 9 120GB HDD
PowerMan FSP250-60GTA/250watt
2)Kingston KVR 1G memory sticks
eMachines eView15L (568) display
....................................... .................
Asus A7V8X-LA Motherboard
AMD 1.8 Thoroughbred
ATI Radeon 9200LE video card
Maxtor DiamondMax 10 120GB HDD
Aspire ATX-AS420/420watt
2)VANTEC 512MB memory sticks
eMachines eView15L (568) display

Both are fully working and do great with MMORPG games for some reason my ATI Radeon 9200LE does not play any FPS games(grey transparent screen) But my ATI 9200SE plays warrock,and wolfenstien ET fine.

Basically the WHOLE lot is going to need a overhaul.

What games in particular are you looking at playing?I decided on keeping my X-PACK-BK/420 case and upgrading it:
....................................... .................................

ASRock 775XFIRE VSTA Motherboard
Intel Pentium 4 640 3.2GHz CPU (775 SOCKET)
Radeon X1300 256MB PCI-Ex16 crossfire
Sapphire X1600 pro PCI-Ex16 crossfire
I ordered all this for under $275 .. only have $325 left in my budget

That is as far as I got please any suggestions on other additions would be great.

I play WOW , STEAM games, mostly into all MMORPG games except Aeria or Acclaim MADE .Wanting a set up that will handle COD and other games in that class. not looking to play Crysis. Thats not much of an upgrade... Whats your total upgrade budget? You will need to upgrade everything becides the HDD and case and dvd drives pretty muchMy budget was $600 and already spent $275, I am just using it for light gaming, email/facebook. I am already pleased with how my PC handles WOW just had extra cash and have been eyeing up the crossfire. I do not store pics music or videos on my PC, so if thats not enough what do you suggest?Wait.... are those your 2 computers you want to upgrade?I am only upgrading one of them the mini ATX Ya... what one is that?yeah and be sure you got a decent video card to go with your pc so you GET decent frame rates. Anything in Nvidia 8-9 SERIES or HD 4000 series would be good and you don't need a high end card. You're playing WOW, which I see is not needing crysis level graphics.I would consider the 4870 a high end card
