then I wouldn't be too concerned.
I'm no expert but for the average user, (like me), hard drive speeds have little noticeable effect. The read/write speed increase is in micro-miliseconds, and is too small for the end user to see any difference.
Similarly with the processors. 2.5 Ghz or 2,26 Ghz is pretty much the same.
What may improve performance is RAM. Too little, especially on Windows 7, will significantly slow down performance. But you don't say what RAM is being offered, so it is difficult to judge that.

which is better if you had a choice a Intel I5 430m, 2.5 ghz with 2 320 hd at 5400 or a intel I5-430m 2.26 ghz with 2 320hd at 7200 running windows 7 Home Premium 64-bit. Does the faster 7200HD make up for the lesser (2.26 to 2.5 ) processor speed or is it a wash. These are at Sams the rest of the spec's on the 2.5ghz sams hasn't posted on the web site yet. The two computers are dv7-3188cl and dv-7-4087c
