Yes, you're right, you absolutely won't save money by doing what I described, that wasn't what I was getting at. You'll spend $3500 either way on the computer, my point was that by splitting the cost and spending like $2k or $2.5k now and then spending another 1k later, you'd stretch out the lifespan of that money.
For instance, you spend $3.5k now all at once, you get an amazing computer, but in about a year, or a year-and-a-half, maybe two years at the very most, you'll need to upgrade again, the graphics card/s specifically, so that will end up being about a year and a half that that $3500 bought you before needing to upgrade again.
Doing what I describe; that is, don't wait to buy a new computer, do it, but don't blow your load all at once; will get you an excellent computer for $2.5k (which I would suggest you do by getting a more modest CPU, as any quad-core that you get will last a good long while, and the difference between the highest end CPU's like the one you listed, and the midrange ones are very very small when it comes to games, and also perhaps not going sli with this system unless you plan on playing on a big screen) and that will last a year or so, and then when that year comes, spend that extra $1k on the new equivalent to the 8800, and get THAT sli. Now with that upgrade that would push your system ahead strong for another year or year and a half, meaning that that same $3500 would last 2.5 years instead of 1.5/2 years.
I mean, don't get me wrong, the system you're planning on getting is excellent, the only thing that would probably need upgrading anytime soon would be the video cards, so either way it's going to be a good purchase. I'm just suggesting this because I think this way you could get more out of your money in the long run.
Then again, if your gf may take away your money later (whos money is being used to buy this, anyways?), then yeah, you're kinda out of options, heh.
But, moving away from my prior suggestion, if I may, I would suggest not spending so much on the CPU anyways, instead, get the very top end Graphics cards and get a cheaper quad-core CPU, as the CPU is not as important for gaming and won't need to be upgraded for a good long while regardless of the specific one you get, just so long as it's quad core.
