256MB GDDR3 GeForce 7800GTX
This EVGA graphics card targets enthusiasts building or restoring a PCI Express x16 system that runs DirectX 9 and OpenGL 2.0 titles. It delivers 24 pixel pipelines at a 450 MHz core clock with 256MB of 256-bit GDDR3 memory clocked at 1200 MHz effective.
Upgrade from AGP or earlier PCIe GPUs
The jump is worth it when moving from an AGP card or a pre-7800 PCI Express GPU that lacks 24 pipelines and 256-bit memory bandwidth. SLI Ready support allows a second identical card for multi-GPU scaling in compatible motherboards and operating systems.
Dual DVI and VIVO for period displays
Two DVI outputs drive digital panels up to 2048 x 1536 at 85 Hz while HDTV and S-Video connections handle analogue TVs or capture devices. A 400 MHz RAMDAC and VIVO support free up separate video-in hardware for editing or PVR tasks.

Questions sur cet article
What PCI Express slot width and physical clearance does the 256-P2-N528-AX need?
The card uses a PCI Express x16 slot and occupies two expansion slots; ensure the case has room for a full-length dual-slot design.
How do I install the GeForce 7800GTX and what step is often missed?
Seat the card firmly in the PCI Express x16 slot, secure the rear bracket screw, then connect the external power cable — that power connector is the step most builders forget.
When will the 256MB GDDR3 memory or cooling need attention?
The 256MB GDDR3 memory is soldered and not replaceable; plan to clean the heatsink fins and replace the thermal paste every few years to keep temperatures stable.
