Hi building a new pc mainly for gaming will need to be able to handle Adobe CS5 applications aswell etc

Out of these four CPU's which one do you guys reccommend for best performance also which one you reccommend for best value/performance.

AMD Athlon II X4 640 -

AMD Phenom II X2 555 Black Edition -

AMD Phenom II X2 560 Black Edition -

AMD Athlon II X4 645 -

Bit of information about other components


GPU - - ATI 5770

Monitor is 1280x1024

4gb DDR3 1600mhz RAM

cheers josh

Personally, if you don't want to overclock, go with the X4 645. Because it has enough raw speed and 4 cores. So gaming and daily tasks, or even gaming with background tasks should all be a breeze. Now, if you are adventurous, then get the 555, because it is a black edition. It can be overclocked with one simple setting in the BIOS. Also it has 6mb l3 cache, which will help you a little in performance also. And, if you are lucky, it can be unlocked to a 3 or 4 core CPU with your board. But do not consider that in the price because it is only like a 50/50 chance you can unlock it to 4 cores. Now, if you've got a little extra money, I would recommend the 955 black edition.

It is 4 cores, 3.2 GHz and the multiplier is unlocked, so overclocking to 3.8GHz on the stock fan is easy if your case has good ventilation. But if budget is the utmost concern, go with the 645 or 555. :kaola:

so its going to be worth spending a little extra to go for the 645 over the 640

are the phenom II x4's out of your price range? (im from the uk so dont know the current american prices.

while a dual core is fine for most games a few games are starting to add quad core support now. such as bad company 2 and crysis 2 will most likely support it.

what sort of games you plaing with it ?

edit: sorry being an idiot :)  i generally expect most people on here to be using dollars :p

Well, it is 100MHz faster out of the box. The 640 and 645 are not unlocked, so if you want more speed, you need to raise the system bus and tweak voltages. Any time you get the Phenom, the CPU is fully unlocked. So if it doesn't feel fast enough to you, then overclocking is a simple multiplier change that won't hurt your board or other components like playing with bus speed. So you are paying about 10 pounds more for 100MHz. Sure, it's not a killer difference, but it is a little faster.

And if you are not doing a large load of tasks, the 555 is 100MHz faster when in single or dual threaded operations. But 4 cores is better for multitasking. For doing one thing at a time, the 555 will win out.

I would hold on save a bit of dough and get the 2500 or 2500k with the intregrated graphics

Why? He is already worried about a $20 difference in CPUs now. Hold off to get a CPU and board double the price? I don't get it.

I think the CPU area should be divided into 3 sections. Intel, AMD, and I'm not sure section... when buying new systems, lol :p . When someone wants to buy AMD, everyone recommends the double or triple priced Intel solution. When someone wants Intel, someone will recommend the cheaper AMD solution. If someone builds an OSX machine, everyone says buy a Mac. If someone wants to buy a Mac, everyone says Hackintosh is cheaper.

This is a battle of funds, not a performance per watt benchmark. We are talking performance per Dollar or this case Pounds. I like AMD and Intel both. So if they want AMD, help them pick the best one that fits into their scheme of things. If they want Intel, help them choose which one. If they don't know, then you can recommend based on personal preference or benchmarks alone.

although the intergrated grpahics on the sandybridge are fairly good id still take a gpu over them

^ +1 Kinth

And besides, he says he wants the 5770 GPU. So why is the 2500 better? Seems he wants AMD. :p

You're welcome. I think you'll be happy with that chip for the price... you can't beat it.

i couldnt find the price of a phenom ii x3 on ebuyer and i think the x4 where quite a bit more expensive

I think he's in the UK... everything is in pounds.

From his budget standpoint... the x3 is double the price though.

I think for his budget it is probably better to get the cheaper 4 core over the more expensive dual core phenom. The dual core is clocked a little higher and is unlocked, but it's not guaranteed to be able to unlock the other 2 cores. Best to get the cheap 4 core if budget is the biggest limiter.

He wants a discrete GPU. Perhaps the 2500 graphics is OK, but a discrete card is going to be better. Also budget is the limiting factor here. The CPU you keep saying is 100 pounds more than the one he is considering.
