Building my first AMD computer, advise me.

[KHADER87]

Hi,

I've been Intel guy for more than 20 years now, but Intel PC components are relatvily high compared to AMD, so I want to build new PC with AMD which will cost way less when using intel.

I came out with these components :

AMD FD8320FRHKBOX FX-8320 FX-Series 8-Core Black Edition (140USD)

MSI Computer Corp ATX Motherboard 970A-G43 (75USD)

Sapphire Radeon R7 260X 2GB GDDR5 OC version (135USD)

I want this Mobo for future crossfie multpile GPU thats why I didnt by the r9 270X.

does the CPU comes with stock fan?

last question , is it worth it comparing to my current PC? as I read the AMD 8320 8 cores CPU is just a bit higher performance than my intel I3 3210.

Intel i3 3210
GTS 450 1 GDDR5
Intel DH61HO Mobo
6GB DDR3

I noticed that the AMD products require way more power, so is a 500Watt PSU enough for the above AMD?

thanks alot guys

The performance difference between the Intel Core i3 CPUs and the AMD FX 8 core CPUs will depend on how well the program utilises multiple cores.
Many games only make heavy use of 1 or 2 cores, so the core i3 comes out ahead.
Any CPU intensive applications that can make full use of the 8 cores will run a lot better on the FX 8-core.
Since the FX 8 core CPUs are much more expensive than the Core i3 CPUs, they are more commonly compared to the Intel i5 CPUs. Virtually all games run better on the Core i5. Again, CPU intensive applications that can make full use of the 8 cores will run better on the FX 8-core.

I wouldn't look at Crossfire for the R7 260X.
A single one of these cards will give you medium settings at 1920x1080, but if you want higher detail settings or resolution then you want a card with more than 2 GB of VRAM.
Adding a second card doesn't help with VRAM because each card ends up with a copy of mostly the same data.
Multi-card configurationms also have unreliable performance compared to a single card.
I wouldn't recommend Crossfire or SLI of any low end card, only the cards near the top of the range where there is no single GPU card available with double the performance of this card.
In your case, an R9 280 would be a much better choice than crossfire R7 260X cards.

For power, it is important to use a quality supply.
The power requirements below are recommendations for the combined +12V rating, which is slose to the maximum continuous power rating on a quality PSU.

AMD FX-8320 = 125W
Intel Core i5 4460 = 84W
R7 260X = 115W
R9 280 = 250W

FX-8320 + 1 x R7 260X (not over-clocked) - recommend +12V rating of 30A or 360W
FX-8320 + 1 x R7 260X (both over-clocked) - recommend +12V rating of 33A or 396W
FX-8320 + 2 x R7 260X (not over-clocked) - recommend +12V rating of 43A or 516W
FX-8320 + 2 x R7 260X (all over-clocked) - recommend +12V rating of 47A or 564W
FX-8320 + 1 x R9 280 (not over-clocked) - recommend +12V rating of 44A or 528W
FX-8320 + 1 x R9 280 (both over-clocked) - recommend +12V rating of 49A or 588W
FX-8320 + 1 x GTX 970 (not over-clocked) - recommend +12V rating of 33A or 396W
FX-8320 + 1 x GTX 970 (both over-clocked) - recommend +12V rating of 35A or 420W

You can take 50W off any of these moving to a Core i5 CPU.

Thanks for the heads up, so for gaming you dont recommend the AMD 8 core as it wont make a difference compared to my i3?

I would recommend a Core i5 over an FX 8 core CPU for games.
The Core i3 will suffer in some situations, particularly online multiplayer games.

You can also just drop a Core i5 3XXX LGA 1155 CPU into your current motherboard too.
Examples; Core i5 3300, 3340, 3450, 3470, 3550, 3570.
Don't get anything with an S or T on the end of the model.

You may also want to consider upgrading your RAM. Is your current 6 GB = 2 x 2GB + 2 x 1GB or some other configuration?
You can get 2 x 4 GB dimms and if your existing memory is as above you might be able to keep the 2 x 2 GB as well.

The money you save on a new motherboard might get you up to the GTX 970.
