Not much, that case means you can only fit in a half height GPU, and the PSU means you can't put a good GPU in anyway. CPU wise you can get the i7 2700 if you can find one.

Whats your budget, in most cases you're better off going new than trying to frankenstein that thing together with good parts.

As long as it can handle games like csgo for example without being under load it's fine and for day to day performance as long as it can handle some multitasking without slowing down dramatically it's fine.

Yeah it will be an improvement, if those are your needs it should do the job. Just don't expect miracles.

Personally i would save your money and build yourself something new based on the Ryzen 5 2400G, but you'll need to double your budget and then some.

OK for now I'll just see how my system runs with the GPU I'm getting and I'll rather save from there or upgrade the CPU depending on how it runs without an
upgraded CPU

Just a heads up, dell tends to put a wattage limit on the pci-e slots on sff and DT models. On my 9010 sff its 50w, on older ones it may be lower like 25w or 35w, so the 1050ti at 75w may not run at all. But many have reported success with the 790, so lets hope its not limited.

The best cpu for the sff 790 is the i7 2600 as it has the HD 2000 inbuilt graphics, the i7 2700 is HD3000 and won't work. I fitted it and those 8 threads make a big difference. I also fitted a zotac LP gtx 1050 ti and have been running it for almost 2 years with no issues. It may be just getting the juice it needs on the raiI but so far so good. I was a bit concerned with TDP due to the low wattage psu but even with 16Gb ram, an ssd and large HD it doesn't get near it's limits. I even tried a little bit of mining :)

OK thanks but the gtx 1050 ti is a 75 watt card and I've been told that the PCI-e connector only gives up to 35 watts so how is your GPU working.

I had a Optiplex 790 SFF (i5-2400) with a Zotac GTX 1050 Ti 4GB in it for years. Ran just fine on the Dell 240W PSU (17 amp +12V rail). Gamed great at 1080p/60Hz.

About the best you can do for improved gaming with that PC until Nvidia comes out with their 1050 Ti replacement.
