Getting new memory- how's crucial?

[Comdrpopnfresh]

I had 2 gigs of ddr... I have an rma issued w/ crucial- they'll give me $120-130 for it, as store credit. I have to spend it on their website.

Is their ballistix good? I have vista, and plan on overclocking, so I'm thinking 4 gigs of 800mhz or 1066mhz.

Is the 1066 worth it, given my nvidia chipset can unlink memory speeds from fsb changes?
here are some links of crucial ddr2 I was looking at:
4gb 4-4-4-12 6400
4gb 4-4-4-12 6400 (tracer)
4gb 4-4-4-12 6400 (red tracer)
2gb 5-5-5-15 8500
2gb 5-5-5-15 8500 (tracer)

I was a bit surprised to find they don't have 8500 in single dimm, 2gb densities. I don't want to spend money for 4gb of 8500, and I'm guessing having 2gb in vista will not be wise, despite the speed. If thats untrue- let me know.

Is their memory worthwhile enough to spend my credit on it? Or should I get my ram on newegg, and spend the credit on flash drives, or an ssd for my laptop?

Crucial is continuing to have reliability issues. The good news is they have a lifetime warranty. Yes OCing the RAM will benefit your performance. The PC2 6400 4-4-4-12 will get you close to 1066 at 5-5-5-15. http://www.crucial.com/store/p...ODULE=BL2KIT25664AA80A

So the 2x2gb 6400 ballistix then? With that being under my credit-limit, is there any difference between the standard ballistix and tracer- besides the LEDs?

Tracers are reported to OC about 5-10 MHz less than ballistix. If you have a window in your case, they will overpower any lights inside that you currently have. But they look pretty fun.
