I have a Gateway DX4850-27E Core i5-2300 Quad-Core 2.8GHz 6GB 1.5TB DVD±RW Windows 7 Home Premium w/HDMI. I need suggestions on what i should upgrade. looking at spending $600.
The psu that comes with that desktop is 300w (if my memory serves me right). Your processor is still good and to game that can still last you couple of years. I would just recommend a new psu and a very high end video card. Also I would also recommend a 8 gb ram upgrade if possible.

First, check your power supply wattage and make sure it can support a video card. Then, get a video card. Then try it out in a game and see how it does. If it isn't performing to the full capability that the card should, then upgrade the CPU to eliminate the bottle neck.
I was lucky enough to have a 400w PSU with my i7 that ran both my R6850 & GTX670 videocards, I ended up getting a new PSU for my 780ti oc but if you have like a 350w or less I would update PSU, you have a decent CPU. I'd get a gtx 770/780 and new PSU if need be.
