From what I've heard so far the Ballistix is great
Peenuts (still laughing at your name, btw!
. This stuff is brand new though, so I'm taking a small risk cause there's no reviews, but plenty of people on various forums are trying it out and having nice results.
Good price -- approx £50 cheaper per 512MB stick than the OCZ I had on my shopping list for the last few months. I just couldn't afford the OCZ 3700EB (way too many bills arrived at once) but I was saving for it anyway, then the Ballistix came along and I was very happy to hear about it. I'll let you know how it goes next weekend, I should have my new machine ready by then *fingers crossed that I don't get any problems*.
