I'm making a new gaming computer one 8800GT will work for all games keeping them on medium right? And then if I get another I can make graphics my ***** correct?
8800GT 512Mb is a great card. What I suggest is you familiarize yourself with some of the review websites such as Tomshardware, Firingsquad, anandtech, and more to see what you can expect, as I'm all about people helping themselves get better.
To answer though, a big part is the resolution you play at. If you use a 15~19" standard or widescreen monitor, you will most certainly max every game on the market EXCEPT World in Conflict and Crysis. If you have a larger monitor, 20"+ you will play near maximum settings or all high. That's the position I was in, with a 21" monitor at 1680x1050 resolution, so I stepped up to SLI (dual 8800GT graphics cards) and now I can make any game bow to me (again... except Crysis, lol).
The 8800GT is high end performance at a low-end cost. If you can afford it, the 512Mb is def superior to the 256.
If you wanted to spend $170~ I would recommend the HD4850 from ATI, which is absolutely astounding and brings ATI back into the competition.
Like I said, best bet to know what you want is to go to google.com and type in something like "8800GT Review" and look at the reviews people give. If they are gaming above your resolution you play (which msot tests start at 21" monitor size unless they are testing budget cards) and they get great FPS at that setting, you know you are set for your.
Just remember: Resolution is important, the higher it is, the more space you have to fill, which means the more power you need to fill it.
Think of it like this. A 17" monitor is a bucket. Now if you wanted to fill a bucket with a house, you would be pretty good at it. A 21" would be a bathtub, a hose would get the job done pretty good, as well, but it will be slower. Anything bigger is like a pool, hose wont cut it, but if you had a fire hose (think high end GFX card) ... or 2! (think SLI or Crossfire) that baby will be full in no time!
Fire hose + Bucket , on the other hand, is just a waste.
I hope that analogy makes some sense.
PS: On SLI, 2 cards in parallel, you need to pay attention more so to having a strong CPU to back them up. If you have a really nice CPU (Quad from Intel) couple with SLI'd 8800GTs you could rival the power of the GTX 280 and surpass it at some points. But then that gets far more complex with motherboards, CPUs, Monitor size, game settings, etc. At that point I would recommend you start doing research
