They list 6 GB, but not that they have Vista 64 bit, which is odd. You need a 64 bit OS for anything over 4 GB. So I assume that's what they mean. Anyways, it would be a fine system.
When it comes to graphics cards, don't judge it by the memory it has. You need to judge it by it's model number. That indicates how fast the GPU is. Another thing to watch out for is the higher end cards have a much higher power cooling system on it, so they are thicker. Look up reviews or call and ask if the computer will accept a double slot video card, and if the power supply in the computer can handle it.
Excellent tips. Much appreciated.
One more thing to consider...would I be better off just paying $829 for this new one below...would it need a video card upgrade immediately as well?
