HELP - need opinions on BIG 28" LCD monitors-Hanns/Viewsonic

Anyone have a 28" Hanns or Viewsonic LCD. I currently have 24" lcd monitor. I am considering getting a Hannspree (Hanns G) 28" monitor. It is a TN panel but not as bad as some I have seen. Does anyone have any experience in using a 28" beast? I know Viewsonic also has one, but Bestbuy has it (Hannspree HF-289HJB)on sale for $530 this week. The dot pitch is .309 as compared to .282 for the 22" and .2865 for the 24" panels. I will be playing RTS games (mostly) and some tactical shooters when not using it for business purposes.

I plan on getting the new RV770 Chipset from ATI when they come out so that should not be an issue.

Should I spring for it or just be satisfied with the 24" I already have. Will I really see a noticable difference?

Thanks
