Cheap Graphics card for 1080p Skyrim

[cyberninja105]

I am looking for a Nvidia graphics card below $100, (if possible below $70) The card needs to run Skyrim on high or medium Settings at 1080p with a FPS of no less then 30fps. I would prefer to get nvidia but if necessary i will settle for something else. Unfortunately I am at a bit of a struggle considering a GTX 750 Ti would be bottlenecked by my processor. I am not going to change the processor because I want to upgrade my Dell Optiplex as much as possible using Factory CPU and motherboard.

Cpu: pentium e2200 2.4ghz dual core (can't overclock)
RAM: 4x2gb 8gb 800mhz
Motherboard: dell optiplex 745
PSU: pending.

So far my best options are GT 630 and GT 740

Main PC:
Intel I5-4460 3.2 Ghz| MSI Twin Frozr V GTX 970| AsRock Z97 Extreme 3| Kingston V300 120gb & Western Digital Caviar Blue 1TB | G.Skill areas 8gb 1600MHz | Cooler Master G550M | Windows 10

I wouldn't go any lower than the gtx 750 ti for a gaming gpu, thats the sweet spot for lower end cards if you venture down further to the GT cards all you will find is a bunch of slugs that barely out perform integrated graphics on modern cpu's. What does the rest of your system look like are you sure your cpu is powerful enough?
