ASUS A8N SLI Deluxe BIOS 1010 mobo
Athlon 64 3500 2.38 GHz Performance Rated at 3.50 GHz
Vista
2 GB DDR dual channel ram
6800 GT PCI-EX 256 DDR3
DX10
2 120 GB hard drives
DVD+RW drive
That is my specs right now and it passes Crysis minimum requirements (PC requirements benchmark) so it should pass minimum for GTA4
There will be no changes to CPU, HD and memory, only get a DVD DL drive
As for the video card Right now i have a 7950 GT 512 DDR3 won at EBay for 55 dollars waiting for me so that'll be an upgrade. I wonder if it'll be enough, if not i don't know if i can get a 9600 due to being a 3.5 year old mobo and 3 year old BIOS
