3007 WFP-HC je bolji od 3008.
3008 ima built-in scaler. A built in scaler

The dirty secret of many of the 30" displays is the digital delay. This is additional time to process the incoming data stream prior to displaying the picture. It's NOT the same as LCD pixel response time but is inclusive of that time.
Would you buy a modern display if it were actually 30+ ms instead of the advertised 6-8 ms?
32 ms delay is two whole frames at 60 fps.
Digital delay has of course zero impact on photo editing or document work. It only matters for gaming and movie playback. In gaming, it means that the player you are shooting at is actually 2 frames away from where you think they are. In movie playback, since there is no facility in nearly any PC playback application to compensate for lip sync delay, you're going to start seeing noticeble lip sync issues. Studies have shown that viewers perceive lip sync problems of 30 ms or greater.
DigitalVersus has tested digital delay on the 3007WFP, 3008WFP, and Samsung 305T. Using their same methods (mirrored display on a CRT and the panel, with the same motion softare as DigitalVersus, photographed with a DSLR), I've tested delay on the Apple 30" Cinema Display and the Gateway XHD3000.
The Dell 3007WFP and the Apple 30" Cinema Display have no appreciable delay. Both use the same LG panel without a scaler.
DigitalVersus tests show 11.5 ms delay for the 3007WFP-HC and my tests show similar results for the Apple. The HP 3065 also uses the same panel and although I haven't formally tested it, in quick evaluation results it seems to have the same negligible delay.
The Samsung 305T and the Gateway XHD3000 have significant delay. Both use the same Samsung panel and in this case the panel itself (and ancillary direct electronics) appear to cause the delay. DigitalVersus tested the Samsung at 29.3 ms and my tests show at least as much on the Gateway. Note my Gateway tests were performed with the scaler disabled. In resolutions supported by the scaler (the Gateway operates only in pass-through mode at 2560x1600 without any color control, etc.) the results would inevitably be worse.
Any scaler is going to add a minimum of 15 ms, and probably 30 ms, just by itself because scalers always buffer at least one full frame for processing.
The Gateway XHD3000 also had a lot more ghosting with its pixel response than the Apple 30" Cinema Display, despite the Apple specs showing slower response.
The Dell 3008WFP has the worst digital delay of the lot, undoubtedly because its scaler does not appear to run in pass-through at native resolution. The scaler is still active at 2560x1600. DigitalVersus shows a 46.6 ms delay which seems very coincidental, i.e. approximately 15 ms native panel delay + 30 ms scaler delay.
I was quite enthusiastic about the 3008WFP until I discovered this issue. At this point I consider the only viable 30" displays for movies & gaming to be the Dell 3007WFP-HC, HP 3065LP and Apple 30" Cinema Display. Of the three, the Apple has the highest quality chassis. The Apple and the HP have about equal backlight uniformity while the Dell can very greatly in uniformity quality from unit to unit and at best is never as good as the Apple & HP. The Dell 3007WFP-HC and the HP have wide-gamut capability while the Apple does not.
All told, it seems like the HP 3065LP is the best overall, with good uniformity, wide gamut, no appreciable delay, and reasonable build quality (better than the 3007WFP-HC, not as good as the brushed-aluminum Apple). If only Apple would get off the stick and release a wide-gamut version!
In summary:
Negligible delay: Dell 3007WFP/3007WFP-HC, Apple 30" Cinema Display, HP LP3065
Significant delay: Samsung 305T, Gateway XHD3000
Unacceptable delay: Dell 3008WFP
