Ran Passmark tests per your suggestion, plus reviewed benchmarks for my Sapphire Radeon Dual-X R9 270X video card against other similar video cards. Although, there are certainly faster video cards available, my R9 270X seems to have fairly reasonable video performance. Overall, the Passmark results look quite good, except HDD performance which is not unexpected given that it is not an SSD.
Given that my previous, now dead, 9 years old ASUS PC, with a Dual core, Core 2 Extreme CPU, running at 3.8Ghz, 8GB ram, Radeon 557, w/1 GB Vram, ran quite well at 30 FPS frame rates, I am still puzzled by the low FPS values, given the significantly more CPU horsepower, plus 4 extra cores and a much more powerful video card, plus 4x CPU ram? By chance, can you share a Passmark run with your system for comparison with my results? I did read where someone stated additional Vram contributed more to XP10 performance improvements than additional CPU memory, once you had at least 4GB of CPU ram.
Attached are my Passmark results. I have not purchased the SW yet and could only capture results as screen shots.
Given my 1 yr old, Radeon R9 270X card only has 2GB GDDR5 ram, it may be worthwhile to upgrade to at least a newer,faster video card, with at least 4GB or more? Perhaps a trip to Microcenter is in order today? ;-)
Thanks for your assistance.
