quad-cores are next to useless for most gaming
So is having a mid to high end 8 series video card. Are we playing GalCiv 2 or Crysis?
Let's compare a GeForce 8600 GT (available for some Dell Inspirons) to the Xbox 360:
GPU clock:
Xbox 360: 500 MHz
GeForce 8600: 540 MHz
GPU memory:
Xbox 360: 10 MB (Is this really supposed to play games??)
GeForce 8600: 256 MB
Regular memory:
Xbox 360: 512 MB
PC from Dell: 2 GB
. . . although I should note that the PC uses a larger OS, which offsets some of that.
Shader pipelines:
Xbox 360: 48
GeForce 8600: 32
Okay, a bit more in the shader side, but not gonna really kill performance.
With a 1450 MHz shader clock on the 8600, that's about 46 billion shader operations per second for the PC, and the 360 claims 48 billion, so they're pretty close.
So for a bit higher price for the video card, you can get a lower end Dell PC with about the same power as the 360.
If you push closer to the $1000 range, their XPS 420s can be outfitted with 8800 GTs, which will easily beat the Xbox 360.
Granted, both systems probably cost a bit more than a basic just-the-xbox, but you
are getting a system that can do more than just play games.
Any gamer worth his salt will tell you that for $130, a 9600GT is the best deal out there budget-wise
Which is precisely why I recently upgraded to one

. It is, however, overkill for most games, save for some of the newest DirectX 10 ones. DirectX 10 support is the primary reason I bought it.
and as far as I'm concerned if you want it prebuilt go take the parts to a shop.
Ah, so there
are options for the average joe that doesn't want to build his own system, but wants one built for gaming. In fact, I know of a few shops in town that will gather parts for and build systems for customers. Don't tell Alfonse, he might throw a fit.
Not to mention it's probably not that difficult to find a local computer geek to help you build a computer either - I'm pretty willing to build a computer system for neighbors and family, or install a component for them.
