intel's not bad since that processor is about 100 dollars less than a x2 3800+ and delivers average perf and its dualcore.
get that intel processor instead. built on a 65nm manufacturing process and if you oc, people have been hitting 4.0+ on average which should give you a good performance gain. that ram is fine, it has a lifetime warranty so its all good if it ever failed on you. i would reccomend a better mobo tho based on the nforce4 chipset.
i would switch to that vid card. same thing as an X850XTPE. i know someone's gona say get nvidia but if you wanna spend below 140 thats the best card to get. also if you want SM3.0 support the x1600pro isn't gona play games at acceptable framerates so theres no point.
