I have had a look at the macworld benchmarks but i didn't really know how to interpret them and the 2.2ghz is way out of my price range but thanks anyway
Understandable. While a great system, they're definitely not cheap!
This is probably the take-home quote from the MacWorld testing as it relates to you:
The 15-inch 2.0GHz quad core Core i7 MacBook Pro was 33 percent faster overall than the 15-inch 2.4GHz dual core Core i5 system introduced last April. The new MacBook Pro’s Handbrake time was 51 percent faster than the older system, while its iTunes encoding times were 24 percent faster. Duplicating and Unzipping files didn’t see much improvement between the systems, and Call of Duty framerate was slower than the older system.
The previous system was/is a very good system, and if you're going to be doing a fair amount of gaming without moving to the high-end MBP, then I think I'd personally stick with the 2010 version. Even better, you can pick up a referb with full warranty and save yourself even more.
This looks pretty dog-gone good!
