[Could this Desktop run GTA IV?]

Sooooo I'm considering getting this desktop and have it be just my gaming/ downloading computer, it seems pretty damn decent, through Craigslist, just wanna know if the specs are high enough to run GTA IV without any major problems, ya know, dedicated video RAM and processor speeds, RAM itself all that. I'll copy paste the specs for y'all uber geeks here (I'm not hatin, I'm an uber nerd..

HP Desktop PC, AMD Phenom QuadCore Processor

didn't realize I can't paste into forum topic, so I'll put what is really needed to make a guess....

500 gig hard drive, 4 gig ram

Windows Vista 64 bit,

Video card, AMD Radeon, 4200 with DVI, VGA connection

Dual-channel Crucial 4GB DDR3-1333 Memory support: Four DIMM sockets, designed to support up to 16GB of DDR3 SDRAM memory, delivering greater platform performance and flexible memory support.

Sound Card: 8 channel high-definition high quality-audio

Gigabit Ethernet Controller - Network Interface 10/100/1000 Base T network interface LAN Chipset Integrated

Just curious if this would have no issues running GTA IV smoothly.

I'm looking at getting this HP g7-1310us 17.3 inch screen, has about 6 gigs of ram,

not sure if the processor mentioned on it is quad core or not but I was wondering

if it could run IV fairly well. My current can run San Andreas but it's just too damn

big.

Could I run a 800GS on my HP?? I think you guys can look up what model I have as I typed in my Product ID... How much would one run me at a local computer repair shop?

Ok so an update, now all I'm getting is the ANNOYING AS SHIT resc10 error that my video memory doesn't have enough to support the game yet I'm on 2Gigs of RAM, it says ingame that I'm running 202/114MB does anyone know how to change this so I don't get the fatal error without upgrading my RAM card?? Thanks much guys.

I was wondering how I can decrease and or increase my specs while ingame to get better drawing rate and FPS and whatnot.

Any help without having to go into my BIOS would be greatly appreciated.

Here's my specs, sorry I'm a bit of a noob still can't get the hang of doing an ingame photo:

Video: 800x600

Texture Quality: Low

Reflection Resolution:Off

Water Quality: Low

Shadow Quality: Off

Texture: Tri-Linear

View Distance: 1

Detail Distance: 1

Vehicle Distance: 1

VSync: Off

Auto Config

Benchmark

My Computer Specs are as follows:

RAM, 2.00G

Windows 7 Home Premium

Again, any help without going into my BIOS and cmd and SafeMode would be greatly appreciated and helpful.

Thanks guys!
