I've been using a very bad setup for the last 2 years, to keep it short and sweet I'll just list the CPU and GPU
AMD A8-5500 APU
AMD HD Radeon 7450
These are 2 terrible components without a doubt so I decided I would take the first step and upgrade the GPU to a XFX AMD Radeon HD 7750. I bought this off of a friend who was using this card 2 days ago and was having no trouble, I can trust this person as I know him in real life and he's in my IT class in college. After installing the new GPU I uninstalled all other GPU drivers and re-installed them. A game I play frequently is CS:GO. I began testing this new card, I set my resolution to 800 x 600 stretched (I used to have to play that) and I was getting FPS as low as 60. On my old and considerably worse card I was always above 70 fps and most of the time floating around the 90-100 mark. I switched to 1920 x 1080 (native resolution) and I was still floating around the 60 fps mark but I was going into the 70s and on average it seemed like I was getting more on 1920 x 1080 than 800 x 600 and that just doesn't make any sense to me at all. I reinstalled steam thinking that there was some sort of problem there but still, the problem continues. I've checked the specs for this card compared to my old one and it is a much better card in terms of everything and I just don't know what the problem is. I just can't understand why this card is underperforming so much and any help would really really be appreciated.
**It's not my PSU, I bought a Corsair 750W one back in January for future proofing.
