My friends PC's HDD died on her and rather than just change that part out she opted rebuild with how antiquated the rest of the build was. Her old rig was ageing too much. It had an FX6100 and an HD7770 GPU. The Case, DVD drive, and PSU came forward from the existing build.
I battled for a good while on going for LGA1150 or LGA1151. In the end I decided on LGA1151 was best. She is wanting the PC to hold up for years to come, and with LGA1151 still being current it will be easier to upgrade with new (currently unreleased) CPU's going down the road. For about $600 I don’t think we did too badly on the parts list. The GPU was a simple choice, she needed 4GB of VRAM and this was the cheapest GPU that offered that.
The benchmarks that I have ran show a huge difference. Passmark went from a 1386.3 on the FX to a 3870.9 on the i5. So I think it was worth the money for a 200% performance gain. In Firestrike, this PC pulled a 4732. I have not run Firestrike yet on the FX build.
The case was an absolute nightmare to work in. No cable management and pour placement of everything. In the end, I got the cables tucked away as much as I could, and I am ready for the berating of PCPP on the cable management. (The 8pin CPU was not long enough to run anyway other than across the board and I will not have the rig long enough to order an extension.)
