My base rig is a Xeon Mod X5460 with Gigabyte GA-P35C-DS3R (rev1) LGA 775 motherboard 8GB DDR3 1600 MHZ (runs at 1333 Mhz) RAM. I would like to change to never chipset with an AMD FM2+ motherboard since my LGA775 motherboard doesn't have proper DDR3, sata3, PCI Express 3.0 or USB 3.1 support. Since everyone going in to Ryzen hype I managed to find a very cheap MSI A68HM motherboard which has all these (second hand 30$). However I am really really new to AMD. I've never used it before. As far as I researched buying and APU would be really stupid.

So what is the best CPU for this motherboard. Or do you have another Motherboard and CPU combination in mind? I wanna go AMD because firstly I wanna learn about AMD and secondly there is a lot of second hand good materials atm. My budget is very tight so please refrain yourself from offering me Ryzen and/or I7 if you are not gonna donate the hardware yourself. : )

Thank you.

"Good" second had AMD is a questionable statement. But, an FX6300 or an FX8320/8350 will be your best choices. A 990 motherboard will be the best choice for the chipset to support those CPUs. You should be able to reuse your DDR3 RAM. You won't get USB 3.1 though you should get 3.0 USB. This is all assuming the AM3 CPU socket.

The A68HM motherboard is an FM2+ socket. Your best choice for a CPU in that motherboard is an 860K.

I think I'll go for 860K since it costs me less than $100 with the mother board. Other options costs almost twice as much. And MSI board has USB 3.1 and PCI-E 3.0. But 860K wouldn't bottleneck a single R9 270X right?

I only ask if I gonna trade of a performance problem with another. X5460 not that bad however the architecture is too old. If there is gonna be a performance problem may be I shouldn't upgrade to amd but just keep on going till it falls apart in my hand. What do you think? Would it worth it?

AMD 8300 series is a solid chip with a decent TDP. Any board that supports that chip is a good choice. Although, I would still look at and consider what features the motherboard, like m.2 slot or USB 3.0/3.1, or even the number of lanes available. The nice thing about AMD, you can mix and match chips with most motherboards and it will work fine. AMD doesnt change sockets as often as Intel. I can drop an AM3/3+ into an FX or FM socket and it will work.

Bottlenecks are hardware dependent, you get what you pay for. The 270 will do better with more cores. Just dont expect the same as if you had it installed with an Intel chip.

I am not in to overclocking that much. But it is a good to have option. And I guess even in the stock speed I will have similar cpu power plus all the benefits of faster infra structures like 1600 mhz DDR3, Sata 3 and PCI-E 3.0. Plus my mother board and cpu still has a little second hand value. So it would be like spending $50 for the upgrade. And this mother board supports 32 GB RAM. While mine supports only 8.

Two questions;

1) So what is the magic motherboard which does do all that? Could you give me few model numbers or if I could steal abit more of your time, links? : )

2) You mentioned Intel CPU however do you mean my Intel CPU (Xeon x5460) or like new I5 or I7 CPUS? I am asking this because I want better performance than mine. If I am gonna get totally new structure (like PCI-E 3.0, FSB 1600+, Sata3 etc.) and get same performance or worst even worse performance than even a $10 change is a waste for me atm. So should I stay with Xeon? I notice you didn't say "the" intel cpu but "an" intel cpu but still wanna clerify. : P

1) its not magic, its depends what your budget is and shop around for one that has the desired socket am2/3/3+ all fit the old chips but dont claim full chip features, obviously am3+ is the most desirable on those. Some people like using pcpartpicker.com when trying to config a system on a budget.

2) The intel reference I was referring to was that every new chip has a new socket and not compatible with previous sockets. What AMD did was an attempt to future proof (talking a decade or more ago) AM2/3/3+/FM+/FX chips by using the same socket with only minor modifications. As far as I am able to explain here, AMD let AM2 chips work on AM3+ boards, same for the FM/FX chips at a performance cost when they really need their own sockets. The drawback was the chips were not exactly backward compatible on the previous sockets, AM3 on AM2 sockets.

In the end, XEON was not designed for gaming so its missing some key instructions, which ones exactly I dont know. That doesnt mean it cant be used for gaming, it means your going in with one hand "kinda" tied behind your back. You can get away with just getting a newer video card, prolly for the same price as updating your system. DX12 takes advantage of more cores so youre fine there, and memory is still king (on the video card).
