One possible drawback to using a GeForce GTX 295 is that you may need to upgrade to a more powerful power suppply.
The software on the installation CD contains EVGA's Precision Overclocking Utility, which provides real-time control of the GPUs core, memory, shader, and fan speeds.
EVGA Precision Software
Note that when the GPU is processing a light workload, such as Windows 2D operations, clock speeds are automatically reduced. When running a 3D application, clock speeds will then increase to their default values.
My test system was recently upgraded from a Core 2 Duo E8500, nForce 680i SLI chipset and DDR2 memory to a Core i7 940, X58 chipset and DDR3 memory. The previous operating system consisted of a Windows XP and Windows Vista dual-boot configuration and was updated to Windows Vista exclusively.
Other than a few minor quirks with powering up the motherboard, which are hopefully resolved with BIOS updates, the system has been stable.
Antialiasing was set to "Override any application setting" in the driver for Oblivion, S.T.A.L.K.E.R and Unreal Tournament 3.
Anisotropic filtering was forced to 8x in the driver for Oblivion.
Here is a photograph of the EVGA GeForce GTX 295 installed in the test system.
Graphics Card Installed
Note that the GeForce GTX 295 requires one 8-pin and one 6-pin PCI-Express power connectors. NVIDIA recommends power connectors that are native to the power supply, although EVGA includes a couple of adapters as accessories.
The performance of the EVGA GeForce GTX 295 was compared to a reference graphics card that is based on NVIDIA's GeForce GTX 280. The GeForce GTX 280 had been their most powerful GPU until the GeForce GTX 285 and GeForce GTX 295 debuted.
The Competition - NVIDIA GeForce GTX 280
Performance is compared to a single GeForce GTX 280 and two GeForce GTX 280s running in SLI at the resolutions of 1680x1050, 1920x1200 and 2560x1600.
