Its definitely not better mate, its a Dual core and hes getting a Quad core, Penryns only has a average speed advantage of about 2% than Conroes, so his Quad will be always faster on Multi threaded Applications than a E8400, and all the Q6600 processors in SL are Latest revision and can be Oced to at least 3.8Ghz with a Very good cooler (that's why I told him to buy the Xigmatek HDT S1283), that is very very fast indeed, and I saw a Experiment showing that E8400 needs to be clocked at 4500Mhz to Reach the Processing power of the stock Q6600, and that's only on Sandra CPU Benchmarks, It still is slow on Cinebench and stuff.
