Hey guys.
I built a PC about 10 yrs ago, so the obvious answer is probably to get a new one. That being said, still looking for some thoughts the situation.
Here are my specs:

MOBO: Gigabyte EX58-Extreme
Processor: 1st Generations Intel Core i7 920
12gig ram
Samsung 250gig SSD (OS drive), Hybrid 750gig
XFX Radeon R9 280

So, to start, I plan on building/buying a new within about a year, depending on finances. Probably spend around 1500.
But for now, my gaming performance is getting to be quite lackluster, as you'd imagine. It's struggling to run the first Witcher at a decent framerate on pretty low settings (35fps wihch waivers quite a bit); I have the 2nd Witcher as well but am not even looking to try it at this point until I have better hardware.

My questions:
I know the SSD i limited by the Mobo bandwidth rate, effectively halving the potential of the SDD, but I cant remember if that is the same for holds true for my GPU. That being said, would it make sense at all to get another matching GPU and run Xfire? I've never done it before so I don't know how hard it is to setup. They are currently on Ebay for anywhere between 60-300 dollars depending on if they are used or new. I can't believe the new in-box ones are that high, but I guess bitcoin mining is still an thing. If i recall properly, they do need to match exactly don't they? Would I realize all that more performance an xfire setup? Or am I really just wasting money I should put towards a new rig down the line.

Thanks, all helpful thoughts on the matter are much appreciated

 
Solution
Weak point in your system is graphics card.
Why don't you just get the one, that you're planning for your next build?

With $1500 budget for whole build, you'd probably go for gpu like gtx 1070 ti, gtx 1080 ?
Apart from having lackluster support, not all games are optimized for SLI/Crossfire. Seriously, i wont bother with that old platform.
I would probably reuse the SSD/SSHD combo and build a new rig bottoms up for $1500. Something like this should be good enough...

Good Answer!

While getting a new PC is obvious, many of us can't afford that option.
I build my PC's a few hundred dollars at a time and use the older stuff in the newer build.
The key is to always get the best thing I can't really afford, but I'm gonna buy it anyway.
That way it will last for a few years before it needs to be upgraded.

I was shocked when I entered my components in PCpartpicker and discovered that I have spent $3,000 on my PC over the past 6 years (based on the oldest thing in my PC now). That includes everything, monitor, speakers, printer, keyboard, etc. My PC alone is probably $2,000.

SkyNetRising, I probably get a card along those lines, or, when the time came for the new pc, something price equivalent at that time. Kinda leaning towards an nVidia, I'e used AMD for the past 15 years with mixed results on the software side of things, but maybe that is no longer an issue with the newer generations; I do like AMD's built-in video capture, although kinda an FPS hit for my current GPU.
The next question would be if I were to just do a straight upgrade for my GPU right now, it would be fairly performance limited by my current mobo would it not? I'm also worried about "future proofing" on the GPU side, meaning, if I buy a card now, what would I be able to get for the same money a year from now when I buy the rig. I know you can't really think about it that way, but consdering there havent been a whole lot of new entries as of late, I figure there should be something shiny and new out by then

Although your motherboard is PCIe 2.0x16 and most graphics cards are PCIe 3.0x16 it won't be much of a performance hit.
Most PCIe 3.0 cards don't use more bandwidth than PCIe 2.0 can provide.
For example SLI setups usually run at x8 + x8 speed with no problems.

There is nothing wrong with getting an awesome GPU now that is a teeny bit imbalanced more than the motherboard, and upgrading the motherboard to catch up later.

 
The highest you can go with that i7 is a 1060 3gb card. That ist gen i7 is somewhere around the performance of a 3rd gen i5 chip, and as you can see there is a bottleneck factor kicking in gradually with the 3rd gen. i5 when you pair it with a 1060 6gb card... https://docs.google.com/spreadsheets/d/1Q7lIYRK5T0ABLvAkgbM_2jJGvbhlep27mR-eRcCy4FA/edit#gid=0
But even with a 1060 3gb card you can get a massive performance boost from your current card... http://gpu.userbenchmark.com/Compare/Nvidia-GTX-1060-3GB-vs-AMD-R9-280/3646vs2241
In a year from now the Nvidia Volta cards will be there which can boast of an impressive performance increase from the current Pascal gen.
