Alright so I just upgraded my Graphics card to a Sapphire AMD Radeon 1gb 6850. The next thing on my list to upgrade is the CPU. I was thinking of getting a AMD A8-3870K (http://www.newegg.com/Product/Product.aspx?Item=N82E16819106001). My question is, is it compatible with my Graphics card and motherboard. My motherboard is a AAHD3-HB(Hibiscus) manufactured by Pegatron. Another question I have is if it will bottleneck my GPU in anyway. Also I have a Corsair GS700W powersupply, will that be ok to run all this? I know its alot of questions but any helpful anwsers are appreiciated. Thanks in advance.

It might work, but you may not get your money's worth; I would contact hp to be sure; it's not listed under "cpu upgrades". If you change the motherboard, you'll need a new windows coa, so don't even think about that. I had no problems swapping power supplies with my compaq, but it was a tight fit, and all those cables on the corsair will need to be tucked away.

I already have the PSU in the computer. I think the reason its not listed in the CPU upgrades is because the CPU is newer then the motherboard. But from what I read I believe it has the same socket and all.

My current CPU is a Quad core A8-3800. I wanted to get this because I play Arma 2 alot and I feel Its being bottlenecked and feel I should be getting more then 25-30 FPS for it. I think the A8-3870k would fix this if it is compatible with my motherboard.

as much as it is likely the motherboard can/will support the cpu, it is highly unlikely that the BIOS will be able to overclock the cpu in a HP machine.

get off the FM1 socket; if the igpu on a liano is not enough to have desirable results when gaming, the weaker cpu side will not be enough to keep up with a discrete card.

To be honest, I don't think upgrading to a 3870k will give you much improvements.

A8-3850 (Assuming this is what you have) = 2.9Ghz - A8-3870k = 3.0Ghz. Both are quad core CPU's based on the same Architecture. The only difference is one is able to be overclocked to higher frequencies...which I HIGHLY doubt your Motherboard can take advantage of.

My advice to you would be to save another $100 and get a AM3+ Motherboard, and use the money you have for the A8-3870k and get the Phenom II 965. Or even better, get an i3-21xx :)

Other than that, your GS700 PSU is MORE than enough for your GPU and any other hardware you may eventually put in. You can even CrossFire 6850's with it! :D

I dont have a A8-3850, I have a A8-3800 which is 2.6 Ghz. I would do the motherboard thing but it kind of seems like a pain to see if it is compatible with all my stuff and I also have NO CLUE whatsoever on how to put it in.

My bad I didn't see the post right :lol:

I still don't think you'll see a big improvement going from 2.6Ghz to 3.0Ghz...I just don't see a $120 value in those 400 Mhz. Not to mention it might not even be compatible. The TDP of the A8-3800 is 65w. Whereas the A8-3850, and 3870k are both 100w :( very high chance the motherboard's max TDP is around 65w-95w knowing OEMs.

Though putting things into a motherboard is very easy! There's plenty of guides around to help you out as well.


**EDIT** Actually nevermind, I just checked the website for compatibility :lol: It might work, but I just don't see your money's worth in a such a small frequency upgrade.

Here are my suggestions -

AMD based - http://www.newegg.com/Product/Product.aspx?Item=N82E16813128519
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103727

Intel based - http://www.newegg.com/Product/Product.aspx?Item=N82E16813157293 (or maybe Z68? some input will be nice here) Friend uses this motherboard, and he's very happy with it.

If you can spend a little more cash, I'd recommend the i5-2400 as well. It's priced at around 189.99 right now I think.

Alright nevermind about that, I just watched a tutorial and it looks like I have to unhook everything just about and seems a tad to hard for me. So final question is do you think this A8-3800 quad core I have is bottlenecking my AMD Radeon 6850 1gb ddr5 by any chance?

The A8-3850 is only slightly faster than the A8-3800. So just take a few points off of the scores that represent the A8-3850.

My current CPU is an X4 955 and I have it running with a GTX 560 Ti, my brother uses the same CPU and frequency with an HD6870 (both a tad bit faster than the 6850, closest thing we have unfortunately). We experience almost no bottlenecking whatsoever.

Looking at those test benches, the difference between the two CPU's is very little so I highly doubt that your CPU is bottlenecking your 6850.

Probably not BUT the AMD APU's are going to be slower than Intel Sandy Bridge and Ivy Bridge CPU's. Unless you are going to be doing a hybrid crossfire APU's aren't worth it. I would rather have the performance with a dedicated video card than an APU with slower performance and hybrid crossfire.

^ i am assuming a mATX board until they post specs on the case size. the only thing known is the size of the board.

You'll need a new windows coa if you change boards, so don't even think about it. If you don't like your system, sell it intact and keep your upgrades (put the old power supply back in and remove the 6850). You may get an opportunity to observe someone building a system someday; take advantage of it and you'll have no problems upgrading.
