Does this upgrade plan make sense?

[Crash425]

Ok, backstory. I built a computer last year at a mid/low pricepoint.
Biostar tforce4 am2 board
amd x2 3800+
7900gt voltmodded
3gig total memory (ocz and crucial)
As my first real system build from scratch I was proud of it, but I'm predictably unsatisfied.

My videocard is inevidably dying a voltmodded death. I need to get a new one fairly soon, but can't imagine a video card upgrade on this mobo/cpu combo. Especially since my motherboard is shitty.

My plan is this,
GIGABYTE GA-P35C-DS3R as a futureproof motherboard solution, should support ddr3 when it gets reasonably priced and intel's next gen when it comes out.

intel dual-core 2160 allendale as a mighty-mite overclocker. known to me through http://www.tomshardware.com/2007/09/...ium_dual_core/

come christmas time the new graphics should be out and my 7900 should be on it's deathbed.

sometime down the road upgrade to ddr3 and a solid next gen cpu.

does this sound as good to you as it does to me?

another reasonable option I was considering was to forego the cheapo cpu with upgrade plans and just drop in a 6750 for long term use.

Upgrading as frequently as you can afford to do so may yield less than expected performance gains. If your upgrades are frequent, you won't ever notice huge performance gains. Therefore, wait as long as you can before you upgrade.

By the time DDR3 is even needed for good performance (2009 according to Intel), there will be a new chipset out. The Eaglelake chipset (G33/P35/X38 replacements) is due out in H1'08. Since current boards won't support the high FSB needed to take advantage of DDR3, I wouldn't bother with it. I'd save my cash and go with the non-C DS3R, and buy a new ~$125 in another ~2yrs.
