sourceThe card, dubbed MSI N260GTX Lightning, will pack 1792MB of memory, as the GTX 295 does, and will be manufactured on a red PCB with dual-slot cooling, dual fans, and five heatpipes. The card also features an 8 + 2 phase power design, including capacitors that support temperatures up to 125C with an advertised lifetime of 5000 hours.
not sure if that is overkill really, i mean i dont think adding that extra ram in there is gonna help it perform @ gtx 280 levels at the average res.
