I'm trying to design an upgradeable gaming computer that would use one good nvidia card now, but be compatible with a SLI upgrade. This is my first build, and I was almost ready to order everything, but now I'm paranoid about everything but the dvd drive! I've got $2000 to spend, but should probably save some for a new monitor. Hard drive space isn't a huge issue, 500 gb should be plenty, so I was considering a raid 0 configuration. I'm pretty hesitant to overclock, but might on the cpu if anyone knows a good air cooling solution for that. Here is my current build, but I would change anything.
I agree. It'll definitely prepare you for the future.
As for CPU overclocking, Q1 of 2008 showed some excellent after-market air coolers.
The Big Typhoon - No, it's not loud, actually very soft. I've used this in a client's computer before, very good. Although it's massive, make sure your case/mobo has room for it.
Another good one is the Scythe - it performs almost as well as the Big Typhoon, and is a little smaller.
Remember, these are EXTREME coolers meant for very hot cases. Assuming you'll be overclocking the CPU, and possibly overclocking both SLI vid cards, they'll be a perfect match. But if it's not in your budget, don't be afraid to try out a cheaper one (but look at the reviews) or go for a Watercooled setup. But be warned, water cooling setups can be awkward to install and can be loud if you don't get a good pump.
