Possible Deal Tuesday on nVidia GeForce GT 240 512MB 128-bit GDDR5 Video Card

Processor Name: Dual-Core Intel Xeon
Processor Speed: 2.66 GHz

Total Number Of Cores: 4

If so, would it be an improvement over the stock video card? How would it affect using my computer? Would it be noisier (I see that it has a fan)?

Chipset Model: NVIDIA GeForce 7300 GT
Bus: PCIe
Slot: Slot-1
PCIe Lane Width: x16
VRAM (Total): 256 MB
Vendor: NVIDIA (0x10de)

Thanks for your thoughts,
