Just wondering if anyone has any experience of upgrading from, say, a GTX560i to for example a GTX66ti or GTX670? Monitor is only 1080p and I'm unlikely to go to three screens. I can get about 60-80fps currently but sometimes feel BF3 doesn't run as it should. For example, in TDM where you get someone shooting close to you it can get a bit blurry and I lose where they are (and die). It isn't the same look as suppressive fire but just feels as though something is not quite right. Running an i7 and checks on that seem to indicate that isn't the bottleneck. Having to upgrade the cooling as it is starting to run hot - as in core temps of in the 90s. Any thoughts appreciated.
