Wierd, I only saw one set of memory in your link, but I didn't notice the MIR on the Patriot.
I prefer the GSkill....it's 4gig, only takes up two memory slots, so it's a bit easier to OC 2x2 then 4x1 if you ever move to 4gig.
Also, that Patriot is spec'd at 2.3V, that's a bit high for me, I'd worry about the RAM dying, unless you use active cooling on it.
The GSkill (and other 4gig kits around that speed) use Powerchip IC's, which usually will run DDR2-1000 at 1.9-2.0V, maybe 2.1V tops, from the reviews I've seen. Lower volts=cooler RAM, so that would tip me to the GSkill.
