Upgrading from a HD 5450


Jan 26, 2013
Hi, I'm looking to upgrade my current card which is a 1GB ATI Radeon HD 5450 and I'm looking to only spend around 100 dollars for the new card.

The games I play the most is CS:GO and occasionally Starcraft II. I wish to buy a graphics card that can handle CS:GO on 1080p on high settings with a decent fps (I currently play on 720p on low settings and get about 35fps).

Other relevant system specs (its an HP I bought about 2 years ago; picture of the inside, http://imgur.com/fSA5y1g
Windows 7 Home Premium 64-bit
Intel(R) Core(TM) i5-760 quad-core processor [2.8GHz, 1MB L2 + 8MB shared L3 cache]
6GB DDR3-1333MHz SDRAM [3 DIMMs]
1TB 7200 rpm SATA 3Gb/s

I've already read http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107.html, and it appears that the HD 7750 seems like the best choice for me, but I would still like some input from you guys about the GeForce GTX 550 Ti and if I should push my budget and get the HD 7770.

My current PSU is a HP OEM of 300W (Here is a picture of the sticker on the PSU, http://imgur.com/HDHEKhI I think regardless of which graphics card I choose I should probably look into getting a better PSU since the word on the street is HP OEM PSU's are of poor quality and it may be risky to run even the HD 7750 :/. So if you could also provide some in put on good quality PSU's that aren't expensive (the lower the better) it would be greatly appreciated.

I'm not looking to change anything else on my computer besides the PSU and the graphics card so please recommend components my computer can handle. Thanks :)
