Hi LC,
Just saw your post. I just recently upgraded my system and bought a new Gigabyte GTX980 4GB (great card btw). It replaced my Gigabyte GTX670 2GB.
You can see it here at this Newegg link
http://www.newegg.com/Product/Product.as...5-423-_-ProductI don't know what size case or power supply you have but it is a better card than what you have at the moment. It is long (11") and the min power supply they recommend is 550W I think.
To help you get by till you save up enough for a better GFX card I'll let you have it for free; to give it a good home. Its in its original box and runs just like new. Never had any problems with it.
As long as you're not on the other side of the world (I'm in California) I'll ship it.
If you're interested and could use it, let me know.
