full system specs? no it is not overkill for a 1080p monitor in fact it is pretty well suited to game at 1080p imo, but if you dont have the system, mind you, the psu to run it it wont matter so tell us your specs and your budget
yeah you will have a nice rig but I would definatley get a new psu from a reliable manufacturer such as antec seasonic corsair or XFX, it will probably run the 6950 fine but there is also a chance that it will crap out on you, so basically if your system stops working you know its the psu imo. But in general the 6950 2 gig is a great choice given your monitor and rig.
its not really the wattage the 550w is sufficient but you are going to want to oc your cpu and gpu then give yourself some extra headroom. Its really that cougar is not a known reliable psu brand so I would switch it out for a reliable one like the one I listed above, if you want to go with something a little cheaper id recommend the corsair builders series psus.
I recommend the GTX560Ti as one of the best values.
1. the most important thing for a gamer is to ensure that the power supply supplies enough current on its 12V rail (or rails). There may be up to FOUR rails, but the total is not added. Never buy a PSU that does not tell you how much current (Amps) the 12V rail(s) supply.
2. 650W is typical for a high-end setup with no more than an HD5870 or 560Ti. Again, pay attention to the Amps for the 12V rail(s).
3. Quality is important.
1. Get a GTX560Ti if in doubt, although there may be slightly better deals or even sales.
2. if a new PSU is required, look at places like NCIX, note the 12V Amperage (recommend at least 25% greater than the card you buy), spend time reading on PSU's in general and NEVER buy a PSU for which you have not found a good review.
im confused since there arent a lot of reviews about these monitors... i chose them because they are readily available from where i live... which would be the better gaming monitor overall in terms of size and clarity?
