Choosing the right GPU

[SuperZac]

Hey all, I'm putting together the parts for my budget rig, and I'm having a lot of trouble choosing the GPU.

I'm deliberating between getting one 6870 or two 5750s. I'm just not sure how accurate the data at https://en.bitcoin.it/wiki/Mining_hardware_comparison is.

Two 5750s get 365mhash/s and are about $180 for both. **[Also, will a 5750 fit in a PCI Express x1 slot? The mobo I'm look at has a x16 and a x1. Not two of either.]
One 6870 gets around the same and is $203.

Advice? Should I be looking at a completely different card? Budget wise I want the most power for as little as possible, and I want to keep it close around $200.

6870 gets 250Ghs in real life and is too expensive at 200$, find it used for half that.
new get a 7790 for 150$ that get you 250Ghs good for btc but bad for ltc

LTC need VRAM so any card that has the full backend, so no 7790 or 7870 tahiti Le, except those 2 prety much anything goes. Find a used 6950 or better yet 2 and unlock the shaders.

I might have put it wrong in my first post, I am very new to this stuff.
