Anyone know a good computer around 700-800 dollars that has quad core and good ram that can hold a lot of world of warcrafts?

Nvidia GeForce 9300GE 256MB with hybrid techology
What do those mean? >< im not as nerdy as i thought cuz i have no idea if that work 700dollars or not
Any suggestions or understanding please reply

I'll break this down for you.
-Your RAM is too much for a 32-bit OS, so then I assume it's gonna have a 64-bit OS. Sucks, better off going 4GB RAM with a 32-bit OS. Also if your Motherboard is supporting dual channels, an odd number of RAM sticks will cut your RAM speed (2x2GB RAM > 5x1GB RAM)
RAM is Random Access Memory. It's for all the things you turn on, IE: running 4 or 5 WoW windows at once. How good your comp can hold them up is dependent on RAM.
-Your hard drive is decent by today's standards. 7200 RPM is ok, if you can get anything higher for a cheaper price go with it. RPM is how fast the disk spins inside the hard drive, resulting in faster saving/deleting.
-You graphics card kinda..sucks? Do you know if it's onboard or an actual separate card? I'm not sure what you mean by hybrid technology either? If you mean SLI, it's pretty worthless right now.
