I'm on a project to revive my old Dell Optiplex 755 DT Which is maxed out at 8GB Ram and a Q6600.
What GPU Would be good for it? I've seen GT1030's in these but always open to see if anything more powerful will fit?
The Dell OptiPlex 755 DT, you own, should be fine with a GTX750Ti. I suggest not going any higher than that due to the fact that after the release of the GTX1000 series cards, any card dropped into an incompatible UEFI BIOS envirnoment will grant you a black screen. On another note, if you did manage to get the GT1030 to wok on your system, I doubt anything more powerful can be dropped in due to the age and lack of power therein of the PSU.
Hmm. Will give a go as currently it's got the dreadful GT610 In it Ughh. I bought the system 4 Years ago from a site that thinks Core 2 Duo Machines can run Fortnite at high settings using GT730's. (https://www.compu-zone.co.uk/index.php/desktop-pcs.html)
If i went for a Zotac 750ti How would i get round the 25W Limit?
It's got a 280W PSU.
I am in the UK And finding a Full Height riser isn't so easy either
