I will advice you on how to drop another £100 but you might not like it. You could get the Q6600 CPU(it's a cheaper quad CPU). It's about 30 pounds cheaper then the Q9300 to get the retail boxed one and 40 pounds cheaper to get the OEM energy efficient version. You could probably also get the RAM about £10 cheaper on eBay. That's £50 and another £50 could be saved if you got a budget case. Other options would be a 600w PSU, 9600GT Graphics Card, 250GB Hard Drive, etc.
