What FPS will I get?

Just got a new monitor:
  • Resolution: 2560x1440
  • Response Time: 8ms
  • Refresh Rate: 75Hz
  • Contrast Ratio: 1000:1
  • Viewing Angle: 178/178 degrees
    • Inputs
      • 2x HDMI
      • 1x DisplayPort
      • 1x Mini DisplayPort
Current System:
Intel Core i5 - 4570 @ 3.6ghz
8gb DDR3
AMD 7950 (925 Core Clock, 1250 Memory Clock, 3gb Ram)

Will i be able to get 100fps w/ CSGO @ native 2k resolution on high settings?

It's difficult to say, so try it and find out. If you're still waiting for the monitor to arrive, simply enable "virtual super resolution" (VSR) and GPU scaling under the display tab in Radeon Settings which should allow you to run the game at 2560x1440 (or something very close to it).

my new monitor has a 75hz refresh rate. should i have vsync on in Radeon Settings or in my CSGO settings?

How much improvement would a GTX 1660 be over my AMD 7950? (CSGO @ 1440p @ high settings.)

Turn all the settings on low with your 7950 and that's what a 1660 will get on high settings.
That is over simplifying things a bit. Especially since the game is more CPU bound than GPU bound at high frame rates.

To the OP, you HD 7950 will easily hold 100fps if you play on medium settings. On high, you won't be able to hold 100, but stay in the 90's for the most part. If you have a 75Hz display, all you need is to sustain over 75, unless you are going to play with vsync off.

Update:

So i just saw this deal on SD and made the purchase: https://www.rakuten.com/shop/dell/product/AA473121/?scid=af_linkshare_208164&PublisherName=Slickdeals+LLC&ranMID=36342&ranEAID=lw9MynSeamY&ranSiteID=lw9MynSeamY-sZFcIzkMJQy9_bzb4ZMR5A&siteID=lw9MynSeamY-sZFcIzkMJQy9_bzb4ZMR5A

OCPC Visiontek RX 580 8gb GDDR5 - $138 after tax

2 questions:
Does my PSU have the proper power connection for this? I'm (100% guessing) thinking this has a single 8pin connector? I have a perfectly working PC Power & Cooling 610 PC (i think i have a 6 + 2pin PCI-E connector, right?)
Will my PSU be able to support this?

Your PSU may be old enough, that it primarily has 6-pin connectors, and not 6+2--pin connectors. You'd probably have to physically check the PSU cables. (I know, a pain.)

Power-wise, you should be OK. I think RX 580 is 150W to 180W (overclocked), and most consumer CPUs are under 150W. Unless you're running something really beefy, like a ThreadRipper 16C or higher, then get a brand-new 850W 80Plus Gold PSU with a 10-year warranty for $150, or better. :)

The specs for that PSU just state that it has dual 6 pin connectors. That PSU came out in 2007 from the looks of it. This was before 6+2 pins existed. So you may be out of luck there. But, lots of new PSU's out there. A 600W is plenty for what you have, even if you upgrade to a newer CPU you will be fine. Well, provided its not a super cheap 600W.

My PSU does indeed have 2x 6pin connectors. and i belive one of the 6-pin connectors has an extra 2-pin connector dangling off of it to make it an 8-pin? I'd be supper happy if it works.

I've read online that some RX 580's have an 8pin + 6pin or 2x 8-pin, is there any chance my video card above will require that?


i'm trying hard not to re-build my PC by installing a new PSU. 8 years ago, i'd love to do it just for kicks, but life keeps me very busy these days. I value something high performance that "just works"

While its true that some OC versions of the 580 have an 8+6 pin setup, the one you linked is a VisionTek, which should have a single 8 pin (or 6+2).

Honestly? I think that you would be safe using an Adapter, Athena Power makes one, single 6-pin to dual 6+2-pin, like $3-5 @ Newegg. I picked up a bunch of them on sale for like $1 ea.

Used one on my friend's Asus ROG STRIX RX 570 4GB card. He has a ThermalTake (new version, with 5-year warranty), TR2-430 430W PSU, but it only had a single 6-pin PCI-E power connector, so we just used the adapter. Should be OK, RX 570 doesn't take more than 100-120W. (*And in theory, 75W of that comes from the PCI-E x16 slot.)

I wouldn't recommend one of those adapters for a 225W TDP GPU, one that takes two 6-pin or 6+2-pin and the 75W from the slot, like my 7950 3GB cards that I used to own. But for an RX 570? Should be fine. Probably fine for an RX 580, but do so AT YOUR OWN RISK. I won't be held responsible if you burn your place down.

Well, technically, a 6-pin is supposed to supply 75W, but an 8-pin can supply 150W. In practice, I guess there's really not much difference in current-carrying capacity between the two, because of the way that they're wired.

But spec-wise, two 6-pin power connectors, is equivalent to one 8-pin power connector.

A better way to compare would be using TDPs. I believe that the RX 580 is something like 150-180W, while the 7950 maybe 220W. That's full-load, balls-to-the-walls numbers.

In practice, the RX 580, being 14nm, should draw a lot less power in most scenarios, especially at idle. (Most RX 580 cards even stop their fans from spinning, while idle at the desktop or watching videos online.)

oh so my PSU should def be good... i'm getting a much more powerful card (2x) that uses less power. I love this PCPower and Cooling PSU, are they still around btw?
