    I clicked the Ebay link 5 minutes after the article posted and the 5800x3d was US $352.93 not 300 with the provided JOLLY15 code. Does it just not work for me or what?

    You have to add it to your cart and then enter the coupon code during the checkout process. It works.

    I found I accidentally included the space before the J in the coupon code. Rookie mistake.

    I have a 5600x with a 3080, play at 1440p. Realistically, what gains could I see with the upgrade?

    Well, depending on what game you're playing it could be anywhere from 5-20%. Here's a couple of example games: RYZEN 7 5800X3D vs RYZEN 5 5600X vs RYZEN 7 5800X | Test in 5 Games | 1440p - YouTube

    But there are a lot of games that don't respond to the extra cache. It's really down to your specific needs. Worth checking what games run better v what you have to see if it's a justifiable upgrade.

    With that said, if we got these deals in Ireland, then I'd be jumping right on that gravy train :tearsofjoy:

    I would see pretty solid gains, in WoW, even over my current 5800x. Poorly threaded titles in general should see substantial gains.

    I went from a 3900x > 5800x3d when it came out and it was a massive boost to everything, even 1440p with a 3080. It felt like i got 2 gens of performance increases in games while i got 1 get of CPU general performance increases. It only slightly loses to the 3900x in multi core work.
