5800k vs 750K and 7730

Direct question:

I am fron Bulgaria, small european country.

I can have 2 systems for the same price. Freaking low end gaming PC...

One of them is based on 5800K APU...

The other one is based on 750K and Powercolor 7730 1GB GDDR5...

I know in US this is impossible, but i want to know, is it worth it to buy 750k+7730, or take the always recommended for low end gaming systems 5800k? Pure performance wise...

I use mainly Unity and some games, as most demanding software. Eventually i'll go for some 3d modeling software. Still experimenting to find one that fits me...

I am a huge AMD fanboy, so no intel options (especially Pentium G whatever number...)

I would do the athon x4 and the 7730 is a better option I would try and get a 7750 or a 7770 though if you can.

7730 is a little bit over my spending limit, so i will take a cheeper case with the 7730 to be able to fit in the price point...

However i'm completely unable to get more powerfull GPU... The difference in price is just to high for me...

I use this website to assemble my parts. This is like the cheapest store in my country...

The 750K is basicly a 5800K APU with the intergrated gpu disabled and a 5800K has a low spec HD6670 on the cpu ( HD 7660D ) 

The 750K with a dedicated video card will give better perfomance

Thanks dude... Now i have another question...

I know for intel, their CPUs set the ram at 1333 and this is why they have XMP profiles...

However, i'm not familliar with the AMD approach at this. I mean my platform is ancient (Athlon 4800+, remember those?, 4GB ddr2, etc...) Now the question is, does AMD have some special approach to ram memories, or it's just plug and play... And is the CL still more important for AMD then the speed, as it was with DDR2 (ddr2 800 c4 was better then ddr2 800 c5 for amd)?

Depends on the motherboard most if not all new amd mobos can read xmp profiles and the newer 'amp' profiles of ram sticks.

The 750K has a native ddr3 1866mhz memory controller (it can take higher depending on the motherboard)

But ram is plug and play it will go in to amd and intel systems without problems.

The speed of the ram isent realy that important for gameing with a dedicated card but sticks with low CL and tight timeings are allways a benefit to your computer around the desktop and general tasks  but gameing you whont notice any differnce(with a dedicated card...if you where useing a APU you whant the fastest you can buy as the integrated graphics will be running off that ram unlike a dedicated card that has much faster ram on the card that it will use)
