The specs say: 8th Generation Intel Core i5/i5k8th Generation Intel Core i7/i7k You may be able to use a 9th Gen i5 or i7. Dell's BIOS v2.0.7 (and later) add support for 9th Gen Coffee Lake S (CFL-S) Refresh processors. So it depends on which CFL-S processors Dell added to BIOS. Search these forums to see what CPU upgrades have been done in this PC model. This PC model has a stock 460 W PSU. So you need to know the minimum recommended PSU size for that card, and you need to know if the stock PSU has an 8-pin PCI-e power connector cable that this card needs. Also keep in mind the max size GPU that fits in this PC is 10.5 inches. So do some searching on these forum for GPU upgrades too. And you will have to disable Secure Boot in BIOS to use any "retail" video card in this PC...
I'm planning on upgrading my 5680 with some new parts, however, I'm not sure if the GTX 1660 Super I ordered is compatible. As for the CPU I've already been told the 10th Gen I5 - 10400 I ordered is not, if true, what CPU of similar speed/price is compatible?
Inspiron 5680 GPU and CPU compatibility?
