The video (Radeon 4850) card on my PC died (Dell i7 core, 12 GB DDR3, 64-bit Windows 7 Home Premium) and I had it replaced with a Radeon 6570 (1 GB DDR3). I figured that going from 512 MG to 1024 MB with DDR3 would provide a boost in performance; however, my Windows Experience Index dropped from 7.3 to 4.7 for Graphics and from 7.2 to 6.3 for Gaming Graphics and my overall score dropped from 5.9 to 4.7. Since I do a lot of graphics work with Photoshop (which uses the graphics memory) I'm not happy. I called XFX tech support and learned that the 6750 has a smaller processor than the 4850 and I would have to go up to at least a 6750 to equal the performance of my old card or up to at least the 6770 to better it. Best Buy has a fairly good price for the 6770 but I don't know if my Samsung LCD TV will handle HDMI 1.4a. My computer monitor (Dell 24" SW2409) is also about 3-years-old but has VGA and DVI connections, which I believe are compatible with the 6770. That card is really more than I need but I'm having problems finding something other than advanced gaming cards.

Any suggestions (bearing in mind that I had Geek Squad install a new 600 watt power supply and the new card)? As long as I buy the new card from them, they will swap the cards just for the difference in card cost.
