walmart/costco laptop help?

[GutPunch]

So im looking to get a new laptop for under $1,000. Possibly even under $800...

My requirements are that I can run PT/PAHUD/pokersites on it and play some decent video games also. I would like a screen bigger than 15.4" but realize that it would probably kick the price up out of my range, so that may not be possible.

I went to my local wal-mart/costco/sam's club and found some decent but not great laptops within my price range..
Anyone have any experience with these? Are they decent/reliable?

Maybe I could find a better deal at pricewatch/fatwallet/ect.. Can anyone reccomend a good laptop within my price range?

Thanks
