I am using Windows 7 Ultimate 64 Bit Edition. I previously had AMD Radeon HD 6450 1 GB Saphire Edition DDR3 GPU. After running for almost 4 years, it had died out. I did not find any alternative, so I had to buy AMD Radeon R5 230 2 GB XFX Edition DDR3 GPU. On the previous GPU, Windows Experience Index showed a rating of 4.7, whereas on installing the new GPU, it shows 4.3. Why this discrepancy? I know that Windows Experience Index is an inaccurate calculation. But still, I had doubts. I have updated the GPU drivers, but the result still shows the same.
