WELL..I WENT AHEAD AND DID IT!
I was at Fry's last night, to get a few LED 120mm case Fans. Just happened to meander over to the Graphics Isle, and saw the EVGA GTX-750 1 GB/GDDR5, for $135.00 with a $10.00 rebate.
All of these past thread posts going back and forth asking nice, seasoned folks like you, whether or not I would benefit from a dedicated GPU, or be simply satisfied using the 4770 CPU's HD 4600 Graphics, I finally went for the card. since I was getting advice from about half of you to get the card, and the half telling me just use the IGPU.
Some decisions have to be made on instinct, and having the GeForce 8600GT for the past seven years, I think overall, I would be better off having this card, than not having it. Besides, maybe someday I may want to a little small time gaming.
(?) When I had set up my 8600GT, in the BIOS I had to direct which graphic controller to use, and I chose the PCI-e. This time with the i7 4770, and the Evga GTX750, will it ask me again, will it auto select, or will they automatically be used together?
Thank you for the kinds words and for all the helpful advice. You all are awesome!! My next purchase?....Either a IPS LED HD 1980x1050, or 1980x1200, and maybe a BD Burner.
