I do not agree with all that,
Here's my point
First, I'm a hard computer user, i push my computers on they very edge of their performances and I never needed more then 6 GB of ram. While i do recommend 8 GB of ram, more then this is completely useless, unless you want do run multiple virtual sessions at once or you want to make a server with multiple tasks and users, there is no point havine more then 8 GB of ram.
Second, I do agree with Mr. Jason on the pre-loaded textures, bt RAM on the video card is not all what you should look for, in fact, for me It wold be a second plan. The prime and most important is the GPU capability, second is the speed of the ram, third the bandwith of the video card and last is the amount of ram If everything else is good, your CPU and the system ram will have to do a bit more work to compensate the need of ram. While all thoses are usually well balanced (except for the ram because the amount ram is usually what the noob customer will look for). Before buying a video card, you should look for the benchmarks over the net and be sure that the video card is supported for your motherboard.
So a shorter way to say that, 8 GB of system ram is completely useless unless if you intend do have extreme hard or spesialisex word for your computer and a good video card is MENDATORY if you want to play games.
My recommendations are (for a good ratio price/power) the GeForce EVGA 275 Superclocked (what I do use now and its way enough for my gamers need) or if you have a little more money, you could buy the EVGA 285.
Good gaming for all G33K5
