Does anyone know if the Dell p/n: 061p37 (Dell Nvidia NVS 510 2GB Video Graphics Card ) was ever made with GDDR5 RAM)? And if so, what are the performance specs? I ran across a seller hawking just such ( p/n: 061p37 with 2GB GDDR5 ) but I can't find specs on it. All I can find is the old GDDR3 version. ??? Thanks in advance!
