GodsPrototype Posted April 5, 2013 Posted April 5, 2013 I want to upgrade my GPU. Right now i have a 6870 1gb, a i7-870 and 8gb of RAM. Would it be wise to upgrade my GPU or will my CPU bottleneck mu GPU if i do so. I was thinking of getting the 7950 oc from sapphire, with 3gb of mem. I have 3 monitors, all 1920x1080. I only use the three monitor setup with DCS. Any advice? [sIGPIC][/sIGPIC]
jctrnacty Posted April 5, 2013 Posted April 5, 2013 I own 7950 from gigabyte and i am very satisfied. 7950 is a good choice even because of 3 gb of vram . The higher resolution the more vram you need. So i think your choice is right although other users say that nvidia card are runnig better the dcs.

Pyroflash Posted April 5, 2013 Posted April 5, 2013 GTX 680, or wait for the 7 series cards. They are fantastic. Like others have said, in your situation, I would sooner get a new Ivy bridge processor because you are most definitely going to run into a largeish CPU bottleneck if you upgrade your GPU right now. However, that is not to say that you shouldn't upgrade. If you upgrade your CPU, you are also going to run into a GPU bottleneck, albeit a significantly smaller one than you would have to deal with given your current processor and a new graphics card. TLDR; Get a new processor, if you have money left over (it's gonna cost you around $6-700 for the CPU upgrade given that you are going to have to buy a new mobo as well), I would go for a new graphics card. Possibly a GTX 660 or 670. If you aim for the sky, you will never hit the ground.
rextar Posted April 5, 2013 Posted April 5, 2013 I agree I'm now running a 660 gtx sc after a gtx 260,on an i5 and got a great performance boost. Intel i5 3.2 ghz 8 GB crucial ram gtx 660 superclocked 2gb 500watt corsair psu win7 64bit extreme pro track ir5 Turtle beach x12
Razor5-1 Posted April 17, 2013 Posted April 17, 2013 How can you tell if you have a CPU bottleneck or a GPU bottleneck? I'm very near to upgrading and wonder will a new card alone give me more fps?
TZeer Posted April 17, 2013 Posted April 17, 2013 If you have 2 screens: Have DCS run on 1 screen. On the other you bring up your task manager to monitor your CPU performance. Then have program like nvidia inspector for nvidia cards, or whatever AMD users use to monitor the GPU usage. Turn off vsync. Start the game and start flying around. Monitor the GPU and CPU usage. Since you have turned off vsync the game will try to show as many FPS as possible. If the GPU is not used @ ~98-100% all the time, your CPU is bottlenecking it. If you GPU is able to run at ~98-100% all the time, but you are still getting FPS drops, it's your GPU that is holding the performance back.
Razor5-1 Posted April 17, 2013 Posted April 17, 2013 (edited) A 1 screen option? I assume this wont work by alt tabbing and checking *EDIT* I just ran DCS, then alt tabbed while still running the game. I have 27% CPU usage and 99% GPU. Guess that solves where my bottleneck is!
