Which one should I buy:
the 4gb version of that ram for 44$ or that 8gb for 75$? I already have 4gb of that same ram 2x2gb. Too bad I wasn't online during the morning shellshocker. dammit
No but really I would go with the 8GB kit if the $30 difference isn't a big deal. Then you could sell your 4GB if you wanted or stick it in another machine, or use it all together (may affect overclockability though).
