Well, the main problem with that RAM is that it's got a CAS rating of 3. That's not too good, and even though you might not think that 2.5 would make much difference, you'd be surprised! You're better off getting the Geil. It's just as reliable, and better performing. Not to mention it's a better value...
If you wanted to go better than that, you could even get this pack
HERE.
It's a GeIL Golden Dragon Dual DDR 1GB(2x512MB) 400MHz Model GD3200-1000DC And there CAS
2 sticks of RAM!! All for $214, still less than the Crucial and a full 1 cas rating lower. That would DEFINITELY improve your performance.
HTH,
