I plan on purchasing a used Dell OptiPlex 790 with intentions to upgrade it for gaming. It has a 2nd gen i5 in it, and is the Mini Tower version as opposed to the SFF and core 2 duo that i'm using now. I have a 1TB Seagate HDD and a crappy GT 730 in my current toaster that are only months old, and will immediately go into the new one once it arrives. Here is a link to the 790 that i will be buying in the next few days:

http://www.ebay.com/itm/Dell-OptiPlex-790-MT-intel-Quad-Core-i5-2400-3-10-GHz-8GB-DDR3-Ram-DVDRW-NO-HDD-/272050066555?_trksid=p2349526.m2548.l4275

The only problem is that the seller doesn't list the PSU, and the very next purchase I plan to make is a GTX 1050, so that the i5 doesn't remain held back by the 730. Would any of you guys be able to tell me what PSU is most likely in this thing? Or is it something that's been refurbished and there's no way to find out? I want to make sure that it will handle the GTX1050, because I would really like to wait on replacing the Power Supply until later on, and be able to have an enjoyable gaming experience in the meantime.


Also, I have done quite a bit of research on it myself, but I realize I could still be wrong.. It seems that the i5 - 2400 would NOT bottleneck this card, hence why I chose the 1050. If that's not accurate, please let me know as well.

Final question, and I almost hate to ask it because you guys have probably answered it over a billion times......If all works out, and the PSU can handle the GTX1050, there's no bottleneck from the cpu, etc.. What kind of benchmarks (ballpark estimate obviously) can I expect? The main game I play is H1Z1:King of the Kill. Right now on my Core 2 duo (3.16 GHz), 8GB RAM, and GT 730 I have to play on crap settings just to get a steady 25-30 fps and be able to play the game without wanting to kill myself. Is it realistic for me to expect a solid 60 fps on medium settings from the 2400 + GTX1050 and 8GB RAM?

Thanks so much guys. I always turn to this community over many other groups i'm in when it comes to decision time, you all never fail me!

Hi, So the first issue you will run into is that the card needs a minimum of a 300 W PSU and that model has a 275 W PSU. I would recommend getting a 500 W PSU because if you are utilizing too much of the PSU's max output it will shorten the life of it (Normally they are around $50). Secondly you shouldn't run into many issues with the CPU bottlenecking with the clockrate being 3.4 GHZ. and lastly I'm not too sure on what the actual numbers will look like but with the build after upgrading the PSU and GPU you should be able to handle H1Z1 or most other games no issue on max settings. I have a 1050 in one of my builds paired with an I3 and I can run on Medium-high with little to no frame drops.
Hope this helps if you have any other...

Definitely helps, you answered all of my questions and within ten minutes of me posting. Thanks so much! I do want to ask a couple more questions. I found a Corsair 430w PSU for 25 bucks, and from what you said that will work fine, but you did suggest 500. Would the extra 70w really be worth double the price? Because, hypothetically of course, I could buy two 430w PSU's and replace the first one if it does die sooner than the 500w would, and still have 50 bucks in it.

Also, just out of curiosity, I'll essentially be upgrading from the core 2 duo to the i5-2400, and from a 235w PSU to a 275w PSU at first. The GT 730, 8GB RAM, and 1TB HDD will all be the same I am using now. I know that i will get significantly less "server lag" or "processor lag" (i've heard both, not sure haha), but will I actually get more FPS right away? Or will I still be playing on STUPID LOW settings at 25 fps because of the GT 730, just smoother from the massive cpu upgrade?

Thanks again for the original answers, I really appreciate it.

ALSO, (sorry forgot last question i had) is the 2GB version of the GTX1050 sufficient? Or are you thinking of the 4GB version while answering?

Yea the 430w PSU should be fine I suggested the 500 just based on what I have done to prevent me having to (in the near future) go in and replace the PSU. About the framerate on higher settings, you should see an immediate impact on having a I5 over a core 2 duo ( Most new phones have a better processor than the core 2 duo). Your framerate will increase due to H1Z1 being a moderately CPU intensive game. But the big difference and also higher quality will be when the new GPU is installed

Out of all the Corsair CX line, the 430w was the best of the bunch, so won't be an issue with that cpu/1050 combo.

If possible, use the 4Gb variant, 2Gb cards really start to suffer in higher end games and this will only get worse with time as new games are making better use of gpu resources.
