Hello milostuvic,

I think the most important question to ask when picking out a new machine is its intended purpose. Is this machine going to be used for gaming?

The most balanced machine from a benchmark standpoint is the AMD setup. Its CPU and Video card fall in the middle. The r7 250 is a fairly weak video card, while that i3 is not the peppiest CPU.

If this machine is for light or general use, all of these would be a good choice.

 

Well it depends in all honesty what the rest of the components are and the budget because from what I am seeing the choices are very different in their own ways . If you are asking which would probably be the most powerful overall I would say the FX 6300 with an R7 260X because that GPU is highest and all the CPU are pretty closely matched. But what worries me is these all sound like their pre-built machines and the problem a lot of times is depending on the budget and brand some of the companies put some very questionable quality parts inside that cause issues.

Good example was a friend of mine bought a pre-built machine that he saw as a good deal that came with an FX 4100 processor, decent case, PSU, ram, and a small GT 610 GPU. He got it for around 300-400 on sale and immediately bought a GTX 560ti for the GPU and was cruising along. Well the machine started after the month warranty crashing randomly (Blue screens) which turned out to be a bad ram stick. He replaced the ram and kept going...Next the PSU stopped randomly which again he replaced and kept going all the way down to the motherboard only 6 months into this machine. He eventually took the case and put in his own choices of components and gave up on the issues and has had no problems since but the moral of this story is that while some machines seem good value you may end up with something that could be a very bad in the long run.

Would you post links to the machines in question and we might be able to tell you how good they are?

 

Thanx for the lenghty reply, I know of your concearn about the quality of parts used in pre built pc-s but I have a 2 year warrenty here, so if anything goes wrong they will repare or replace it for free. Posting the machines is a bit difficoult since they are in a different lenguage. I will post about the pc when he (my friend) gets it.

 

I can read if the site is in a different language thanks to google translator. But as long as you understand and keep track of things I would just say make sure your happy with it before hand.

Like I said if your wanting something for the now, I would say that FX 6300 and R7 260X will be the best of the choices.

 

Here are the complete specs for the amd machine: (I found them in a post)
'CPU AM3+ AMD FX-6300, 3.50GHz BOX Black Edition 32nm
'Memory DIMM DDR3 8GB 1600MHz Silicon Power CL11,
'AMD Radeon R7 260X Powercolor OC 1GB DDR5,
'HDD SATA3 7200 1TB Toshiba DT01ACA100, 32MB
'DVD+/-RW Samsung SH-224DB/BEBE/SATA/ black, 24XDVD/16xDVD-RAM
'Case 560W Blueberry BC-M42-560, Black
'Case cooler 90x90mm
'MB AM3+ 760G Gigabyte GA-78LMT-S2PV VGA,

 

Well as long as you get it for a deal that would not be to bad in all honesty as the specs while not stellar in some spots are still a lot better than many machines I have seen. I would say you should be more than fine with that overall setup as the only part I would view as a bit questionable would be the power supply since its one of those case and PSU combos (On top of being an abnormal wattage). But the machine is low power enough that Iwould think it would not make a difference so I would not fret and go with that for your choice if I was in your shoes!
