i5 4570 vs FX-8320 based gaming rig

[Lucifius]

I need help chosing which CPU to include in my new rig. Apart from the CPU and motherboard, it is probably going to look like this:

GPU: Powercolor HD 7950
RAM: G.Skill Ripjaws X 8GB
HDD: WD Blue 1TB
SSD: Samsung 840 EVO 120gb
PSU: OCZ Modxstream 600W
Case: Corsair 300r
CPU Cooler: CM Hyper 212 EVO

My motherboard of choice for the i5 would be ASrock Fatal1ty H87, H87 because that is as high as my budget can go, and i wouldn't really need the Z87 for a non-K i5, and for the AMD, from what i've read, the gigabyte ga-990fxa-ud3 would be the best choice.

Would there be a significant difference in gaming between these two, and if there wouldn't, which one would you recommend based on future upgrading capatibilities?

Here's a comparison of the two CPUs:

AMD FX-8320 vs Intel Core i5-4570

The Intel chip is slightly better, but costs more. The AMD has eight cores where the i5 has four. This is irrelevant for gaming, but I can tell you as an FX-8350 owner, you can do a lot more stuff simultaneously with an eight core than you can with a quad. Not much slows it down.

If it were me, I'd go with the AMD chip. It's cheaper and the price/performance ratio is higher. If you're only running single threaded games, then go for the i5 as it will perform better.

The intel chip is slightly better for gaming, but for future long term upgrading - intel changes sockets virtually every update these days.

AMD, however tend to stick to sockets for a lot longer. There's a fair chance that the AM3+ socket will allow more generations of newer AMD chips than an intel socket would.

and for the AMD, from what i've read, the gigabyte ga-990fxa-ud3 would be the best choice.

I have the ud3 and would not buy it again. A ud5 or ud7 would be a better choice. I'm in the process of changing out my ud3 for a Crossfire V Formula Z asus mb. I've read that the ud3 has a new Rev4.0 now and it's improved from the Rev3.0 that has bugs.

You may want more PSU than the 600 watt Corsair. A 750+ would allow you to add a second gpu for crossfire in the future.

Firstly, thank you all for the responses. AMD appeals to me a bit more than intel now, but there's still time to decide, so responses are still welcome

Well, having a strict budget, a ud5 and an 800w psu aren't really an option. I understand that the more expensive board would be a better option, but is there a reason not to consider the ud3? I need it to overclock well, if it doesn't, well, i'll need another board

I'm not planning on crossfiring in the future, and most good 800w psu's would be out of my budget.

Maybe you could squeeze this into your budget? Remember the PSU is the heart of the rig and for sure helps stable over clocking.
Newegg.com - SeaSonic S12G-750 750W ATX12V / EPS12V 80 PLUS GOLD Certified Active PFC Power Supply, Intel Haswell Ready

Many good mobo's and I've had 7 perfect working MSI's and this one would do the job for sure.

Or this ASUS.

That ASUS board rocks. I wish I had picked that one up when I bought mine. I see it's cheaper now, darn it.

Several good threads at www.overclockers.com on over clocking with amd and the ga990fxa. I would be sure and get the Rev 4.0 ud-3, not the Rev3.0. I know all to will about the budget, but the ud-5 is only about $20 usd more than the ud-3 and it's money well spent. The ud-5 was better voltage regulation and is more robust all around.

The 750 watt Corsair psu is about $20 usd more than the 600 watt version, again it's money will spent. I would consider the psu as more important than the mobo.

I think you would have a much better over clocking experience with these two upgrades from your original list. I can also recommend ASUS boards, good over clock potential from bios. I've been having the RMA from hell with a asus itx board, four trips in the big brown truck and they still can' get it right. The customer service side has been very good, the repair side...not so much.
