I have an old computer with ASUS P5Q Deluxe Intel P45 Motherboard which currently is using GForce 550 Ti graphics card which I gave to my son to play games like Minecraft, Roblox, Gary's Mode etc but recently he get more into more advanced games which require better graphics card.

I have tried to install XFX Radeon HD6870 which I have used few years back but for some reason it did not worked with that mobo (no signal to the monitor).

My question what will be good/max card which can be used with that mobo? There is 750W PSU so it should be fine to handle anything from 5 years back ;)


CPU is Core2Quad Q9650 (Yorkfield)

  • What's your budget? You could theoretically put a 3090, so price is key :D.

  • @Salocor somewhere between $100-$160 Aug 10, 2021 at 1:00
  • Alright I'll find something in that price range

  • Hm, in theory the Hd6870 should just work on that board. I'D suggest to do some troubleshooting before purchasing a new GPU. - Did you connect the extra power cables to the GPU? - Does the GPU work in another computer? - Did you uninstall the Nvidia drivers before installing the AMD GPU?

The GTX 970 looks like a good card. It gets 50% on UserBenchmark. My Radeon HD 6950 gets 18% and can play AAA titles at decent framerates, so 50% should be more than enough. On eBay, you can get a GTX 970 for around $160 if you do some searching/bidding.

  • Any particular reason why XFX Radeon HD6870 on that mobo will not provide signal to the monitor? Aug 10, 2021 at 13:55
  • I’d check the comment that skippy left on the original post.
