At the same size, it'll be noticeable, if you move up in size, less so.
Looking through the Newegg website they currently have some BIG deals going on: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100161617%20600012673%20600012217%208000&IsNodeId=1&bop=And&order=PRICE&page=1
The link is up-to-date at time of posting and I've filtered the selections for IPS/VA 1080 panels sorted in price order from low to high.
Me, I'd look for an IPS or even a VA type panel (very wide viewing angles, excellent colours) rather than a 'fast' TN one, in this kind of price territory, you'll be looking at a 60Hz refresh rate so the 'slow' IPS/VA panels won't actually be any slower.
