Well, here's a few suggestions.
Honestly, computer parts are always in constant evolution. Therefore, it really doesn't matter much if you buy it one or a year after. Be warned, some technological breakthroughs have more impact than others. In the end, it all depends on your needs.
First of, 2GB DDR2 Corsair Dominator Memory (assuming 800mhz) for 160$US is not worth it in my opinion. You can get OCZ 2GB XTC Gold DDR2-800 for under 90$ and I'm even seeing Patriot Signature Line 2GB DDR2-800 for under 80$ canadian. I've had the OCZ 2GB XTC Gold DDR2-800 running for 8 months now and have not yet been disappointed.
Second, if you're wondering if you should wait for the GeForce 90 series, ask yourself two questions:
- For what purpose are you buying this new computer? Is it for Huxley, or it is actually to play the newer upcoming games and not necessarily Huxley?
My answer: If you're only buying a new computer in order to play Huxley, well then all I can say is: wait. Depending where you're ordering from, it can take less than a week to receive your items.
- If you want to get a GeForce 90 series later on, why not buy the 8800 GTS 320 mb for now and upgrade it when they do come out (and if you do really need it)?
Moreover, as far as the motherboard, I wouldn't look to far. No need for a gazillion gadgets on it (like the P5W DH Deluxe, which I bought and was a total waste). I do like the fact that my motherboard supports Quadcore processors but in all honesty, by the time I upgrade my processor, I'll just change the whole damn thing.
At last, why did I ask for your monitor? Well, the only way I could see SLI being useful, is if you would actually play on high resolution (2560X1600 for example). Therefore, if you own a LCD monitor (highest resolution of lets say 1280X1024), it would be a total waste. Furthermore, if playing at 1280X1024 satisfies you, then it is yet again a total waste imo. You should know that having two video cards does NOT double your frame rate... unfortunately.
Anyways, hope this helps.
