Are these specs good enough to run Battlefield 3 on max setting with no lag?

Intel Core i5-3570k 3.4GHz
64 bit Quad-Core Processor
6MB L3 Cache
8GB DDR3 1333
500GB SATA II
NVIDIA Geforce GTX 660 2GB
500Watt
ASROCK H61M-HVS, uATX

Could this spec handle BF3 and the rest of the highest end game on max setting with no lag? and about how much fps would i get on average with this spec on max settings? Im thinking the processor and the ram might be too weak since its only a i5 and the ram being only 1333 mhz.

Planning on running this BF3 on a 1280 x800 resolution or a little bit higher.

Get a real motherboard, that H61 will hold your CPU back and prevent later expansion. As for your question, you should be able to run BF3 maxed smoothly at 1280 x 800.

It should run it very well but there's not much out there that will max it perfectly. Turning down MSAA would help a lot.
