Hi, i'm building my first PC soon, and was for sure going AMD all the way (Phenom II X4 975BE and up), then someone said check out the i5, and i did but i didn't seem like it was much better stat wise (both around 3.4 GHz) and then i looked at a benchmark and it said the i5 was about 30-50% faster in all categories, i'm going to be gaming, but i still want a powerful CPU to fold@home. and it also seems the i7 isn't any better but costs 100+$ more. help?
even tho the clock cycles are teh same frequency, the workload that is completed after each cycle is different.
there are 2 different concepts with current cpus:
do less work but at a higher frequency. OR do more work but at a lower frequency.
right now amd aims for a higher frequency with less work completed per cycle and intel does the other.
the fact is that intel cpus can both do more work and overclock a boatload than their amd counterparts. thats why intel>amd.
Im not 100% sure about this but I think the reason i7 is a better chip than i5 is because it has virtual cores where i5 just has its 4 cores. Having the 4 extra virtual ones increases the performance thus the price difference.

Are you joking?...Surely you know what HT is?
@OP i5 2500k can be used to fold bigadv, you need native linux to run it. performance/$ wise 2500k is unbeatable at the minute.
So what would be the most cost-effective and cheaper than sandy bridge setup for an AMD Phenom II build for overclocking so it would match or at least keep up with the sandy bridge...if even possible?
Price - Performance the i5 2500k is top dog.
Unless you can unlock yourself a Phenom II x2 555
Which is half the cost and will perform almost exactly like a 955.
Sandy Bridge is just the place to be right now, it's a sad time for AMD processors.
AFAIk nothing from AMD keeps up with Sandy Bridge at the minute, Intel are just too good. AMD engineers are all asleep...
Nah just kidding hehehe
Check out this anadtech bench of the 2500k and the X6 1100T Black Edition (the best amd chip on market to my knowledge), both at same clocks, and the AMD chip even has TWO MORE CORES plus more L2 cache...but it still has no chance.
On that test, the 2500k won 33 out of 37 comparisons between the two. Very impressive Intel

guys he's comparing AMD and Intel, not Intel i5 to Intel i7.
Its not possible, AMD's architecture is too far behind. Bulldozer is coming out in September, and it is going to at least partially catch them up performance wise.
Though Intel will release SB-E and IB soon enough and AMD will be far behind again.
Here are some charts that should show you the difference, also why not to buy a 6 core thuban for a gaming build (still pII arch)
Your main factors should be.
2. Number Of Cores (Higher is better)
3. Stock Clock Speed (Higher is better)
I hope you don't actually think this is true, more cores does not mean better for gaming since most games aren't encoded for multi threading.
Stock clock speed is largely irrelevant.
IDK though, a lot of the things you have been saying are quite foolish.

I play FPS and some open world games guys, and i want to pwn battlefield 3. and the folding thing was an afterthought, i'm gonna do like 95% gaming on this thing.

You don't need much to pwn Battlefield 3, at least in the current Alpha stage. I get like 50fps outdoors with my setup as is. If you had a Sandy Bridge with a decent card you'd destroy that game.
A friend of mine has a Phenom 965 with a 560Ti SOC and he gets like 90fps outdoors staring in the middle of a populated map. (Just another reference.)
Go with the i5. The whole point of what people are saying is:
Best-bang-for-buck-processor in terms of price-to-performance is the i5 2500K. For a gaming machine seeing 95% use in just gaming alone, you can't get a better processor for the money right now.
they don't have increased textures, dx 11, or anything high end running in the alpha right now...
