It is 11 years old card. But yes that was one of the best generations of card from AMD. I had a 5450 which was my first graphics card. I was very happy that I could finally play new games on it. Good times indeed.
I actually have a ATI 5850 1GB (stock cooler... no mining) running in a Core i7-920 system, I was thinking of sticking a ASUS 7870 2GB Direct CU II in there but it only runs XP. Runs older games just peachy which is all I wanted.
I have a problem getting rid of older hardware, quite a bit I give away but some I just keep.
I find the integrated graphics useful for this situation. It lets you still use the PC and play some old games while waiting for a new card. Sometimes these really old cards have driver issues today, even though they are fast enough for those games.
The 5000 series was a really good release for AMD. Full stack of cards, performance and power consumption were all spot on. I only had a lowly Power Color 5750, but it served me well. Played lots of Bad Company 2 and Battlefield 3 with it.
I think AMD should have reserved the RX 5000 series for RDNA2 cards. As a sort of return to form.
