ok,want more performance?
replace the 2133MHz RAM,it useless to anyone. the applications that can use the extra MHz are very rare and still dont give a big performance boost.
for MOBO get a Asus M5A97 R2.0
for CPU Get a 8350/8320 whatever fits your budget (8350 is better)
for GPU try ramping it up to a 280x,the extra performace will be very visible
for HDD get a caviar blue/black whatever is the cheapest. id never pay more money for a "better" HDD
other than that,looks nice
tell me how much it will cost now,since i dont live in the UK i dunno
