looking at an AMD X2 6000 Dual core processor 3 ghz which has 2 mb of cahe but for the extra buck i could have an intel with 4mb of cache does it make any real dent in the performace area

The Core 2 Duo is a completely different animal than the X2. The difference in L2 cache size should have very little to do with your decision. http://products.amd.com/en-us/Deskt...

but if you had 2 cpus that were similar other then the cache, the cache size can make a difference in performance, it depends what the PC is doing, affects different things differently. eg. gaming versus video encoding etc. The cache is one thing that differentiates eg a Pentium 4 2.4ghx from a Celeron 2.4ghz

gona be used for gameing The simplest solutions are the best and they are often save you money

The point is, you can't make direct comparisons between Intel & AMD CPUs because they use different technologies. It would help if you mentioned which Core 2 Duo you're considering. I had a look at newegg & the X2 6000+ sells for $160 (retail) or $179 (OEM). I would think it would be the other way around? It's the same CPU in either case...check the OPNs: http://products.amd.com/en-us/Deskt... And notice that the 6000+ is a 125W CPU, so a decent PSU is an absolute necessity. I'll take a stab at it & guess that you're asking about the E6550. They seem to be fairly comparable, depending on the benchmark test, but I'd say the nod goes to the E6550: http://www23.tomshardware.com/cpu_2...

Cache doesn't come into play unless you are doing some pretty hefty processing. If you're a typical pc user that doesn't do a lot of heavy computing, then the amount of l2 cache will make no diff.

just wana make shure the games i wanna eventualy play ut03 and all those others that requre decent spec wont be affected i.e i notice a lag when there is a big kaboom or the frames suddenly go slomo The simplest solutions are the best and they are often save you money
