it will function, as PCIe slot is backward compatible, there might be some performance impact, but won't be noticable in gaming performance [especially if u only use 1 monitor and mainstream resolution]
although the system are pretty old, it might bottleneck the GPU, and most games doesn't support 2 CPU as far as i know, so the game might gonna use 1 CPU instead of 2, resulting in even bigger bottleneck...
u should also check whether the PSU can handle the new GPU too
as for productivity work, the GPU should improve the performance too, but again, the CPU might be the one holding it back...
expect some performance difference
PS: this is from gaming perspective, as u don't specify the PC's purpose
Yeah it's for gaming. The power supply should be fine. I didn't know that about he cpu's though.
it's pretty old gen, + it's only dual core, as far as i know, even my GTX 1050ti got bottlenecked by a pentium [just giving the big picture here] because most games right now already starting to use more than 4 core, and with that new GPU, the CPU would be the main problem here
my suggestions:
if u're on a tight budget, buy the GPU, it's fine, it'll work, but don't expect it's maximum performance since the GPU will be bottlenecked, but there should be some massive improvement despite that bottleneck, stick with the rig till u can save up enough for a new PC
if u already had the budget, do replace em, it's much better that way
since the build aren't fit for gaming to begin with [as games are not optimized for dual CPU build]
PS:
as it is a prebuilt, i'm a bit concerned with the PSU, would u mind checking the PSU wattage and the 12V rail [on the label] these should give me some insight on whether the PSU fit for the task or not
