Obsessive Nvidia fan here o7 I wouldn't go with the 1050 TI at all. Its more or less Nvidia's new first time video card. It's a great budget card if you're upgrading from onboard graphics to a video card. Performance wise though it's about on par with the GTX 670 as I recall. The OP probably wouldn't see any real performance increase at all. It's better to sock the money away and spring for a 1070 at least for the best performance boost on a budget if they wanna go the Nvidia route.
To the OP, the score you got as many have said is a good score and I wouldn't worry at all. Deffo do like what was suggested and have all the dust blown out of the case and all fan blades wiped clean and the heatsink as well.
