Hey guys

Just planning a pc build (something that will play mw3) and I'm starting at CPU's which seems logical since they are the "heart" of the computer right

Just looking through the comparisons of AMD and Intel have to offer:

prices from http://www.auspcmarket.com.au/products/15/

AMD Phenom 2 AM3 840 (3.2Ghz x 4) / $128.7 = 12.8Ghz/$128.7 = 0.099 Ghz/$
AMD Phenom 2 AM3 955 BE (3.2 x 4) / $140.8 = 0.091
AMD Phenom 2 AM3 965 BE (3.4 x 4) / $161.7 = 0.084

AMD Phenom 2 x6 1055t (2.8 x 6) / $192.5 = 0.087
AMD Phenom 2 x6 1075t (3.0 x 6) / $214.5 = 0.083
AMD Phenom 2 x6 1090t (3.2 x 6) / $218.9 = 0.087
AMD Phenom 2 x6 1100tBE (3.3 x 6) / $248.6 = 0.079

compared to intel's 4 core options:

Core i5 2300 2.8Ghz x 4 / $210.1 = 0.053 Ghz/$
Core i5 2310 2.9 x 4 / 222.2 = 0.052
Core i5 2400 3.1 x 4 / 233.2 = 0.053
Core i5 2500 3.3 x 4 / 243.1 = 0.054
Core i5 2500K 3.3 x 4 / 261.8 = 0.050

I won't go any further 'cos it starts to get above $300!

So in other words you can get the AMD 4 x 3.2Ghz for ~$128 while the Intel 4 x 3.1Ghz is ~$233, a hundred dollars more for less clockspeed!

I'm considering getting the Phenom 2 x6 1100t for my gaming set up yet people keep saying this is a bad choice and that intel is better in some indescribable way, now I'm not some fanboy of AMD I just want the best Performance and AMD are better right? unless I'm missing something here

any suggestions are welcome!
cheers

PS Maybe it all makes no difference and I should just get a cheap CPU and spend the money on the GPU, does the CPU choice effect gaming?

Clock frequency isn't a measure of performance! It turns out that an Intel core gets significantly more work done per clock interval than current AMD offerings, i.e., an Intel core vs an AMD core at the same clock speed is faster. This is why Intel remains the performance king. AMD competes on price only for now, until they can get something more competitive out the door.

As said, there are many things other than clock speed that affects performance. In gaming even the i3 2100 rivals any of amds offerings. http://www.tomshardware.com/reviews/gaming-llano-proces...

Right now the best price/performance is the 2500k at the high end. Gpu does need to be paired with a capable cpu to get the best performance. It might help if I know what your whole budget is. I would suggest you make a build thread or fill this out. http://www.tomshardware.com/forum/261222-31-build-advic...

In resolutions below 2500x1600, the Intel i5 SB rigs will nearly always produce higher framerates, despite any percieved clock speed deficit. Looking at typical cpu scaling charts per 100 MH increse in clock speed, the X4/X6 rigs would need to be clocked to about 4.5 GHz to achieve framerate parity with i5-2500 at stock 3.3 Ghz clocks....

The only reason anyone tries talking you out of the more expensive X6 units over the X4 is that they offer no advantage in games yet...; 4 cores, faster clockspeeds, less money, better performance....

Whats you budget? When considering what CPU to buy I would work it out this way.
1st find out the price of all the components you really need ie HDD, RAM, Case etc basically everything except your CPU, motherboard and GPU. You will not know exactly what PSU you need until you work out the GPU but guess based on a good 600W.
2nd you now know roughly what you can spend on your CPU board and GPU and for a gaming build you want to spend around 2 thirds to half on the GPU.
Currently Intel have a better choice than AMD at almost every price point, good optrions cheapest 1st are:
Pentium G840/G850 these beat all the Athlons at similar prices
I3 2100 these beat all the Phenoms at similar prices to a 965BE
I5 2500K This beats and other CPU for sale by anyone for gaming
Hope this helps.

Currently Intel CPU beats in performance as well as value for money but motherboard is more costly than AMD.... In total, Intel built will be little bit costlier than AMD for similar performance range...

thanks for the replies guys it's a real eye opener

like I said it's just for gaming, my budget is around $1000-1,500

say I choose the i5 2500k can i still use ATI graphics cards in Cross fire?

Yes. Any combination of an AMD card or an NVidia card with an Intel or AMD CPU works fine. If you want to SLI or X-fire look for a mobo that supports it (there are Intel and AMD mobos that support either or both multi-GPU setups).

2500K is the best choice just make sure you get a board tghat supports crossfire at least 8X/8X or 16x/16X even better avoid anything with a 4X second PCIE slot
