try and go for one of the six core thubans, i got one to replace the quad 925 i killed and have noticed many areas that perform better plus i got 20 frames more than i used to in battlefield and why not you can get the 1090 for 160 on sale these days. and really the quads are just so old now a days
I'd rather pay the $60 for two extra cores that I could possibly use in a multithreaded application than pay $60 for 8GB more of RAM that I might never be able to utilize fully. 8GB is enough for the majority of users and I doubt you would be able to use anything more than 8GB for the lifetime of the rig. 16GB could be mainstream by the time your rig is considered outdated but that is at least 5 years from now.
