best graphics card for pcie 2.0 x16

Solution
I can't find a list of compatible CPUs, single or dual - so I can't answer that.

As for the GPU, given the relative 'power' of the Xeon, I wouldn't go higher than a GTX1050, personally.
A GTX1080TI :lol:

It's too simplistic to look just at the PCIe revision - there's many more factors.
Strictly speaking, the 1080TI is the "best" (consumer) card that could run in it..... but chances are pretty good you've got a CPU that'll bottlneck it, potentially hard.

What are your system components currently, and what is your budget for the upgrade?
 


I have HP xw6400

Do you have dual Xeon's? Or just the one?

Unfortunately, an ~8 year old Xeon (or two) isn't going to be a great pairing for tasks like Gaming. What are you specifically looking to achieve here?

Your PSU (as far as I can tell), is a 575W unit of decent quality..... but at ~8 years old, I wouldn't be too-too confident in it's "575W" ability.

65W TDP CPU (x2?) + 50W for the balance of the components puts you at 115-180W.

System *should* be sufficient to just drop something like a GTX1050 in there.
A 1050TI is a stronger card, but I suspect it would be under-utilizing in that config.
 


I have two xeons 5150 and i want to put at my pc one of xeon x5492. Does one processor will work or i need two. So what do you advice me to do for proceesor and graphics
