Userbenchmark is reliable but it's not a crystal ball. Both of those GPUs are very very weak. Userbenchmark ranks them at within 10% of each other meaning one will do better in some games and the other better in other games. The only way you can know for sure is by finding benchmarks of both cards for CS:GO. This Haswell iGPU beats the 9400 GT by 300% Nvidia GeForce 9400 GT vs Intel HD 4600 (Desktop 1.25 GHz) Userbenchmark Effective 3D Gaming GPU Speed: 2.02% vs 8.12% Nvidia GeForce 9400 GT - 392nd / 502 Intel HD 4600 (Desktop 1.25 GHz) - 211th / 502 And a 970 wins by 4000% Nvidia GeForce 9400 GT vs GTX 970 Userbenchmark Effective 3D Gaming GPU Speed: 2.02% vs 84% Nvidia GeForce 9400 GT - 392nd / 502 Nvidia GTX 970 - 11th / 502 So both of those cards are more or less at the bottom of the scale either way.

From the faq on "health": http://www.userbenchmark.com/Faq/What-is-the-UBM-PC-status/94 "A health score/percentile based on relative component performance (50% is normal). A component achieves a status of 75% when it's faster than 75 out of 100 results for the same component. PC status is the average status of all the components in a system." So a "health" score of 46% means you are just slightly below average.

Any luck? Did you find the problem?

When task manager reports the system idle process at 80% that means that everything else combined is using 20%. You need to look at the other processes and find out which ones account for the 20%.

well I am not psychic but since the 128GB 850 pro costs $90 let me know who's going to pay me $10 to take a a 128GB 840 pro off their hands, you?

at 240GB you definitely want the Samsung 850, they are around 60% faster at writing: UserBenchmark: Intel 730 Series 240GB vs Samsung 850 Pro 256GB Effective SSD Speed: 82.3% vs 99.2% Intel 730 Series 240GB - 129th / 659 Samsung 850 Pro 256GB - 21st / 659 At 480GB its a much closer call, but the 850 Pro still leads on just about every metric: UserBenchmark: Intel 730 Series 480GB vs Samsung 850 Pro 512GB Effective SSD Speed: 94.5% vs 101% Intel 730 Series 480GB - 35th / 659 Samsung 850 Pro 512GB - 17th / 659

go for an i3-4160. Its a bit more expensive but far faster for single core stuff. Also despite having just two real cores, its actually faster for quad core workloads which is as many cores as the vast majority of games are able to use simultaneously: UserBenchmark: Intel Core i3-4160 vs AMD FX-6300 Effective CPU Speed: 74% vs 56.6% Intel Core i3-4160 - 72nd / 826 AMD FX-6300 - 212th / 826

The i5 is a far better general purpose CPU, although it looses slightly to the 8350 when it's maxed out with all four cores running at 100%, it doesn't loose by much. At all other times (which is the vast majority of the time) the i5 is around 25% faster. UserBenchmark: Intel Core i5-4590 vs AMD FX-8350 Effective CPU Speed: 79.7% vs 63.6% Intel Core i5-4590 - 36th / 826 AMD FX-8350 - 144th / 826

No - not even close, but the price difference is more like $30 (still not worth it). UserBenchmark: Samsung 850 Pro 128GB vs 850 Evo 120GB Effective SSD Speed: 95.3% vs 94.4% Samsung 850 Pro 128GB - 31st / 659 Samsung 850 Evo 120GB - 36th / 659

Vacuum cleaning while the case is still screwed on shouldn't pose any risk at all, a lot less than you continuing to use it while the fan is going ape.

get a powerful vacuum cleaner and hold it over the air vents, if that doesn't help or you are feeling more adventurous then take it apart and vacuum it from the inside.

An overclocked 750 lags a stock 750 ti by around 5-10%. UserBenchmark: Nvidia GTX 750 vs GTX 750 Ti Effective 3D Gaming GPU Speed: 24.4 vs 28.9 % Nvidia GTX 750 - 71st / 485 Nvidia GTX 750 Ti - 58th / 485

Those manufacturers read/write figures are overly optimistic. Here are some results from 7 people that actually own the drive: http://ssd.userbenchmark.com/SpeedTest/18436/TS1TSSD370 500 read / 411 write is more realistic.

fair enough, you won't be disappointed coming from a mechanical drive

The Ultra Plus is a pretty good drive but if you fork out another $50 you can get the new 512GB MX100: http://www.newegg.com/global/uk/Product/Product.aspx?Item=N82E16820148821&cm_re=mx100-_-20-148-821-_-Product which is a faster drive with double the capacity for just 50% more cash.
