I have a OptiPlex I5 Quad core @ 3.2 ghz 16 meg RAM running SSD drive only lack is 512 meg Video Card. Wondering if best approach is to get 4 gig Video card and another 16 GIG of Ram? currently running Workspace and Photoshop Standalone. Workspace needs at least 2 gig video card. Have 2 Macs with insufficient specs to use IMHO. Could buy 2019 IMAC but a lot of money not sure how much better performance. Any suggestion on good not overpriced cards?
