Need some help with my GPU

[SomeRandomScavenger]

So I've been having some issues and a really can't figure wtf is going on. I'm building my friend a budget gaming PC for Christmas but there seems to be something wrong with the Gigabyte Radeon RX460 WINDFORCE OC 4Gb? I have the 2 Gb version in my own pc and it runs benchmark valley at ~80fps on ultra but this one can barely run it at ~20fps with frequent pauses on ultra. I have also noticed that the computer runs fine without the GPU or the drivers (Crimson ReLive 16.12.1) installed but slows down massively one I insert the GPU and install the drivers. My computer is running an Intel Pentium G3260 @ 3.3 GHz 2 cores and the one I am building my friend has an Intel I5 2400 @ 3.3 GHz  4 cores and they both have 12Gb DDR3 1333 MHz ram. Can someone please help me I need to get this fixed ASAP

i think the CPU is bottleneck your Graphics card. Test the card in a different pc that has a better cpu and see if you get better frame rate to prove it.

I only have one at hand as I am at my friend's house building it and I highly doubt it is being bottlenecked by the cpu as the I5's single thread performance is extremely slightly lower than the Pentium and it has just under double the multi-core performance

Stop with the word bottleneck. It's become the new "future proofing" word to be used everywhere.

still need to figure out what is going on tho

wait is It possible the MOBO has something to do with it? I bought an old dell OptiPlex 990 and just added ram and the GPU?

Have you checked game DVR settings?

I can assure you that is not the issue as the processor is clocked at the same speed (3.3 GHz) and has more cores

Go to xbox then click on settings and disable the gameDVR by default it is enabled which results in fps drops so check that out
