Question about PCIE!

So I just recently started looking up specs of my PC to know a little more about it, and I've run into PCIE. After some info-gathering I got this question: Is 8x PCIe 2.0 common these days (I know today's systems have PCIe 3.0, but is the 8x like a really low number?) and will it hold back performance of say a GTX 1070? Thanks!

PCIe 2.0 x8 is not fantastic in this day and age, but it won't do much to the performance of a GTX 1070. What's your CPU though? That might still bottleneck performance.

My CPU is the core i7-2600. I'm actually more worried about the ram speed of 1333MHz. See, I would like to game at a 144Hz monitor and make full use of it. Thinking about upgrading to a GTX 1070..

The theoretical maximum bandwidth of PCI-e 3.0 is 8GT/s, or nearly 1GB/s per lane:

  PCI-e 1.0 PCI-e 2.x PCI-e 3.0 PCI-e 4.x
x1 250MB/s 500MB/s 985MB/s 1969MB/s
x4 1000MB/s 2000MB/s 3940MB/s 7876MB/s
x8 2000MB/s 4000MB/s 7880MB/s 15752MB/s
x16 4000MB/s 8000MB/s 15760MB/s 31504MB/s

Most board since have been PCI-E gen 3.0, Gen 2.0x16 is generally regarded as still usable with 0 bottle necking, not sure about PCI-e 2.0 x8

The 2600 isn't bad, and the 1333 RAM shouldn't hurt too much. But it might fall a bit short for 144Hz gaming. Depends what games you run, of course.

Ouch. My system's awful compared to today's.

Yeah I didn't think it would be capable but whatever, hehe. Will get a GTX 1070 if prices magically drop after the 1070 Ti (don't think so but yea), to then upgrade the MOBO + CPU later.

On paper, yes BUT, all is not lost!

Damn. 96% of peformance I’ll take that any day. So do you think I can run a 144Hz monitor fully? Or is it really my ram that will hold back high framerates?

I dont think your ram speed will hold back frame rates, possibly your ram quantity. (if you only had 4gb for example) then that could affect performance across the board when you cap out

Are you telling me I can run let's say Battlefield 1 (Low settings, GTX 1070, 12GB DDR3-1333, i7-2600 @ 3.2/3.8 GHz, 1080p) at at least 144 FPS?
