Re: Intel Core i7 4770 @ 3.40GHz with 16gb ram, a really good compatible graphics card with DP out on the graphics card GTX 1060 (6Gb better than 3GB) is best match for cpu. They are considered a perfect balance. if you just want a video card that can run 4k [NAME], then GT1030 (okayish, not really good but will do) or GTX 1050 (good but not really good).
Hi all.    I have an old'ish XPS 8700 which came with a NVIDIA GeForce GTX 650 Ti which, sadly has no DP output. I've also just purchased a new Dell Ultrasharp 43 4K USB-C Monitor so I'm having to use the HDMI output instead of the DP.  Whilst it appears to be running at 60hz, which is better than the 30hz the 38 inch Dell curved monitor that I recently sent back as I was thoroughly underwhelmed by it, I'm obviously still missing out on the quality on offer. In which case, given that I'm running a Intel Core i7 4770 @ 3.40GHz with 16gb ram, can anyone suggest a really good compatible graphics card with DP out on the graphics card please? I don't want to replace the PC as I like Windows 8.1, certainly better than 10 ( I produce lot's of email folders), so your suggestions would be muchly appreciated here. Thanks in advance. Phil
