By the way you don't need PC6000 to get a great overclock. Most of the people who have Venice chips were using PC3200 anyway. Though ninja linked up some incredable deals for the speed the G-skillls latency is so high you should really concider something else. PC6000 will not run on AMD motherboards anyway. You'll have to manually underclock it. AMD's Rev. E chips, like your 3000+, support up to DDR500 (PC4000). However in your price range you can't afford some good PC4000, I know of some great ram but it's way too pricey.
This stuff should give you a great overclock without breaking the bank. OCz is a big brand so it should work fine with your motherboard. I would only bother checking if for some reason you're getting an obscure brand.
