Hello, all, I've been trying to figure this problem out for a long while now. I've looked up guides on ways to improve performance on my computer but nothing seems to work. This is the worst part, my score has actually dropped when switching to a 7870 from my 6850. What I notice is that my GPU and CPU load never reach 99/100%, so it is kind of hard to tell if my CPU is really bottlenecking my GPU or not. I am aware from research that there may be other bottlenecks but since I'm not all that experienced at putting together rigs (this is my first one), it's kind of hard for me to identify the problem, and I was hoping that someone could please help me with this situation.
I'm starting to regret the "upgrade" and think that I should have purchased a better CPU and mobo first, but you can find a few results on Google on the question of whether or not the CPU I have could bottleneck the 7870, the majority stated that an OC'd CPU would be fine.
The average score I received with my 6850 was 4800 on 1280x720 Medium. Even that seemed kind of low to me, but I don't know, I might just be wrong. I have tried searching for people in a similar situation like mine, but all I have found is maybe two or three people with only the same GPU, and those people got scores in the 5k's on Maximum 1080p.
Here are my results with my 7870 on the exact same settings as the 6850:
My CPU has had a stable OC from 3.2GHz to 3.8GHz.
Here are my system specs: XFX Double D FX-787A-CDFC Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card Western Digital WD Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive - OEM G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL ASUS M4A88TD-V EVO/USB3 AM3 AMD 880G HDMI SATA 6Gb/s USB 3.0 ATX AMD Motherboard Rosewill Green Series RG630-S12 630W Continuous @40Â°C,80 PLUS BRONZE Certified, Single 12V Rail, Active PFC "Compatible with Core i7,i5" Power Supply AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor HDZ955FBGMBOX
I appreciate any suggestions or recommendations (like hardware upgrades), and any help. Thank you for your time.
I have a pretty low budget, btw, it took a while to save up for that 7870 so you can see how I feel kind of bad about how things have turned out...
I only mention this so that nobody goes "Just buy [insert all this expensive stuff here]" lol
[EDIT] I've found stuff about a "power saving mode" for GPUs causing low load and therefore low clocks, but I have no idea how the GPU could have its power saving mode. Is that just the performance plan or something? Could that even be it?
[EDIT 2] I have also found about how the CPU load might not actually show up as full load because it means the game is efficiently using all 4 cores. I have also turned off all power saving features from the BIOS. Still would appreciate any info.. thanks. Edited, Apr 13th 2013 3:43am by RedMage1993 Edited, Apr 13th 2013 1:57pm by RedMage1993
