GT 440 and Radeon 6670 - Old but okay for 1440p desktop ?

[Popcornuk]

I have 2 PCs and want to upgrade my monitor. I don't play any games but do a lot of work on my PC. Would a old GT 440 and Radeon 6670 be okay for 1440p ? If so, would it be good for 144hz (just desktop) ? As I know even when not playing games 144hz can be good.

Thanks for any advice. Other specs are Win 10, 16gb ram, i7 and 6 core Phenom.

The 6670 is the better gpu as for 144hz if its just desktop it should hit that refresh rate but not sure what connection is needed.

The 6670 will do 1440p/144Hz via DisplayPort, assuming your specific model has that connection (some have a VGA port instead).

Thanks. What is the max hz that dual link can go up to ? As I have a dual link KVM (not HDMI or DP).

What DVI can manage at 1440p seems to vary a lot by setup, but around 90Hz seems to be the answer without extensive tinkering. I'll quote somebody else here:

DVI can handle 100hz at 1440p, but you will need the amd or NVidia pixel clock patcher for it to work. This is a bandwidth of over 400 MHz pixel clock.
I've tested a display scaled (NOT DSR or VSR) 2560x1440@100hz and 398.40 MHz pixel clock successfully over DVI (using a 1080p monitor, no less). So yes it can work.

120hz will most definitely NOT work. You *MAY* get it to work via a custom resolution by lowering the "Horizontal total" value to drop the kHz rate and pixel clock a bit.
Someone did manage a 519 MHz pixel clock over DVI (185 hz refreh rate!!!) when it's supposed to be limited to 450 MHz, so anything is possible.
