First and foremost, this is going to be a long question. I've come onto Tom's hardware to see of anyone can help me. I'm looking for a cheap gaming rig that can run CS GO at 60+ fps; and I want to base it off of a Dell Optiplex 755 core 2 quad 2.66ghz 4gb ram Windows 7 2013 80gb hdd.

Before you tell me no, let me tell you about my current setup. I'm running off of a HP Pavillion g6 notebook PC, Windows 10 home, AMD a6-4400m APU w/radeon(tm) graphics. It also has 4gb of ram. There is virtually no graphics at all, but runs cs go at medium settings. The only thing wrong with this is that I get and avg of 20 fps on deathmatch, and 30 fps on matchmaking. It very ocassionally dips to 22 when shooting. Matchmaking is playable, but deathmatch lags and runs bad. I get about 60 fps when I look into a corner on the edge of the map. The HP is also very loud.
That sucks right? Anyways back the the dell. I was thinking of upgrading the psu right away to a 500w psu, then adding a fitting $100-$130 geforce, or asus gpu. I would then install a used like-new western digital 500gb hdd. I think I could upgrade the ram whenever I want.

This comes to a total price of $270.

I don't know if the motherboard can support everything though. Please let me know if this would work, and if so would it be better than my current laptop. Thank you for your time.

The Dell Optiplex 755 comes if four different form factors.

1) Mini-Tower: Able to add a single slot width graphics card and probably accept any standard power supply upgrade.
2) Desktop: Able to add a single slot width, low-profile graphics card and possibly upgrade to a better Dell proprietary power supply.
3) Small Form Factor (SFF): Able to add a single slot width, low-profile graphics card and possibly upgrade to a better Dell proprietary power supply.
4) Ultra Small Form Factor (USFF): Unable to upgrade.

Any upgrade recommendations would be dependent on which form fact PC you have.

I like the GTX750Ti for these computers. It's the fastest card that doesn't need a power cable, so you can use you old PSU. It comes in low profile, and make sure if it's more than 1 slot wide it's not longer than 6 3/4" or it will hit the rear of the cooler housing. Crucial.com lists DDR2-1066, Dell says DDR2-800,and that 1066 won't work. This list shows a few more CPUs than the Dell manual. Get latest BIOS before CPU swap. dual slot GPUs can be modded to fit easily.

F886J 2.83GHz Yorkfield Quad Core Q9550 12MB, 1333FSB, E0
N650J 2.66GHz Yorkfield Quad Core Q9400, 6MB, 1333FSB, R0

Those 3 above were validated by Dell engineers, and below the rest of general processors from another list. (Thanks kisianik)
