nvidia card for optishot

[mikecor]

Hi,
Im in the process of getting optishot and wanted to know what nvidia card I should go for.
My current computer is 1yr old intel i 7 2600K CPU @ 3.4GHz running win 7 Pro 64bit,Mboard Asus P8Z68V PRO/GEN3
I have 32GB RAM.The video card in it now is nvidia GTS 450.I use this card originally because it is dedicated to music,so graphics were not that important. I believe it only has 1GB memory.can you suggest a better nvidia card that you have success with?I want to run optishot on my 50" TV

1)Asus GF GT630 PCI-E 2.0, 4GB 128-bit DDR3, 810 / 1100 MHz , DVI, HDMI, VGA, Fan ?-$86.00
2)Asus GF GTX660 DirectCU II OC Edition PCI-E 3.0, 2GB ENGTX660-DC-$258.00

Would have thought nvidia GTS 450 would run optishot graphics.

website says min specs are Graphics Card: 256MB Adapter RAM, OpenGL 2.0 Support, and the latest graphics card drivers installed

save your $

Thanks CPA,
I dont know what I was thinking.I was getting mixed up with 128bit instead of video ram which 450 has 1GB.So should be ok.Cant wait to get my opti from Cory.Then hope that lighting,club recognition(I unfortunately have TM)though some have not struck any problems with TM goes.
