My current Desktop PC is a HP p7-1003w: (HD7850 2gb GPU & 500w PSU added)

http://h20000.www2.hp.com/bizsupport/Te ... Id=5080737

CPU is AMD Athlon II X4 650 3.2ghz Quad.
--

Now here is my question, would the following give any kind of performance gain that would be noticeable, mainly gaming and general use.

CPU: (AMD A6-5400K Trinity 3.6GHz (3.8GHz Turbo))
http://www.newegg.com/Product/Product.a ... 6819113282

MoBo:
http://www.newegg.com/Product/Product.a ... 6813157334


I can get a really good deal, but I don't want to change if the gain wouldn't be much.

Thanks guys!


edit: What does it mean by Turbo, is that the stock speed or does it vary depending on certain tasks..?!

The only issue with swapping your motherboard is that your copy of Windows won't work, as it's licensed to the motherboard of the original computer. So you can't re-activate it on the new motherboard. Other than that, it looks fine.

Turbo is a mode where if the processor determines it has a light load, it turns off one or more cores and increases the clock speed on the others.

I thought I could deactivate the Win 7 key on this PC and use it on new hardware..?!

edit: What about the performance gain, would there be any?

You can't with OEM keys, as they're tied to the motherboard. Especially with keys from Dell, HP, etc. They're usually such that you can't use them on anything else other than the computer it came with.

So there is no way of upgrading a pre-built PC without buying a new copy of Windows?

Not to the extent you're upgrading. If you were just upgrading the CPU or adding more RAM or a video card, it'd be different.

OK, well Windows aside, would this be an upgrade or not? I can't find any benchmarks comparing the two so I need some advice on whether I should do it or not.

Yes and anything would pretty much be an upgrade so you don't need benchmarks to prove anything. But if you want to know what you're getting into: http://www.tomshardware.com/reviews/a10 ... ,3224.html

It would be an upgrade although it may not be much depending on what you're doing with it. The closest comparison I found was here with an Athlon II x4 645 vs an A8 5600K. Your board however does support Phenom II processors and something like a Phenom II would be a nice upgrade although you'd have to stick to ones with a TDP of 95W or less but you would be able to continue to use the same Windows license.

I made the same post on another forum I frequent:
http://www.gamefaqs.com/boards/916373-pc/65568131

...and I got people saying it wouldn't be an upgrade...I'm confused now, although I have better faith in you guys here.

Essentially the reason that it would be an upgrade is because the Trinity APU has more cache available and the CPU cores are a bit more efficient than your previous gen Athlon CPU. I'm curious, just how good of a deal are you getting on this APU & motherboard? Actually looking again it wouldn't be an upgrade, I thought you were looking at a quad core trinity for some reason but that's a dual core part. It might perform the same in some games but it's not going to be an upgrade.

I'm on the fence if it's an upgrade or not. CPU performance wise? Per core it would definitely be better. But benchmarks I've seen don't seem to make it worthwhile to go for a full system makeover.

If you're looking for gaming performance OP, a graphics card with the money you were willing to spend would probably give you more performance than the bottom tier APU and a new motherboard. You also don't have to worry about Windows.

It was going to be 40$ total, for the board and CPU. A friend bought it a month or so back, but he just upgraded again and wanted to see if I wanted it.

sorry for double post*

You mention the cache is better on the APU, but at this link it shows mine being higher:

...Less I'm looking at it wrong.

While generally higher amounts of cache do attribute to performance improvements, this is really architecture dependent. For instance, a Pentium 4 is crippled unless you give it lots of cache because of the way it was designed. Its competitor, the Athlon XP, was more efficient at handling processing so adding more cache didn't do anything to help it much. Athlon XP's had half the amount of cache as the Pentium 4, but they were often neck and neck in performance (if not the Athlon being better).

So more cache does not automatically mean improved performance between architectures.
