Resolved Question

New PC is slower than old PC

by pajamageek / February 22, 2014 9:55 PM PST

Built computer with what I thought were a better motherboard, CPU, & RAM and upgraded Windows 7 to 8.1. My new computer boots fast, runs fine and seemed ok until I benchmarked its performance with 3DMark - and found out I was getting significantly less FPS and 3DMark scores than my old setup.

Old Computer
Motherboard - Alienware 046MHW, Intel P67, 1155
CPU - Intel i7-2600, 3.4GHz
GPU - GeForce GTX 760
OS HD - 250GB Samsung 840 EVO SSD
RAM - 16GB Hyundai Electronics 1333MHz
PSU - 875 Watt Dell Power Supply
OS - Windows 7 Home Premium

New Computer
Motherboard - Gigabyte GA-Z87-DS3H, ATX 1150
CPU - Intel i7-4770K, 3.5GHz
GPU - GeForce GTX 760
OS HD - 250GB Samsung 840 EVO SSD
RAM - 16GB Corsair Vengeance Pro 1600MHz
PSU - 850 Watt XFX P1-850B-BFX
OS - Windows 8.1

I got virtually no improvement in FPS or score when running Fire Strike Benchmark in 3D Mark when I made the following adjustments:

1. Set NVIDIA Control Panel to max performance instead of quality.
2. Changed Windows settings to best performance rather than appearance.
3. Minimized the number of start-up programs.
4. Optimized SSD performance with Samsung Magician software.

Any help or advice in trying to figure what's wrong with my new configuration and/or components would be appreciated. Thank you.

Seems right. Did you read this?

"Our tests demonstrate fairly little difference between a $225 LGA 1155 Core i5-2500K and a $1000 LGA 2011 Core i7-3960X, even when three-way graphics card configurations are involved. It turns out that memory bandwidth and PCIe throughput don't hold back the performance of existing Sandy Bridge-based machines. ",3106-4.html

The change of OS and drivers mean it may take awhile to approach or pass up the old PC. But given the hardware changes alone I would not expect higher numbers in the benchmarks you noted.

Thanks for the link and info

I had not read that article you pointed out. If I would have seen that article I probably would have made a different purchase decision and saved some money. I guess I thought an i7-4700 upgrade from i7-2600 in and of itself would increase my computer gaming performance. Guess I was wrong. Thanks for the prompt reply.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
