I built my computer nearly 6 years ago, which currently contains the following:
Intel Core 2 Quad Q6600 2.40GHZ
2 x 1GB DDR2
Sapphire Radeon HD2600XT 256MB
1 x 500GB Sata HDD
2 x 250 IDE HDD
1 x DVD writer
The video card has recently been dropping signal to the monitor, though the problem ceased when I tried a GT 610 in it.
I am looking to purchase a new video card and have been going back and forth with my decision.
I initially figured I should upgrade to one of the newer releases, such as the 7770 or 650 ti. Though I'm now second guessing the choice as I'm not sure my computer could even handle the card.
I don't plan on upgrading to a new computer any time soon, but would like the card to work in a future build. Though if it wouldn't fit my current system well I suppose I am better off with an older card.
I also do not use the computer for any gaming.
Should I go for one of these newer cards or should I look for an older model?
If you will not be gaming or video editing and the like, you will not need a good graphics card. The Core 2 Quad and a budget GPU (like GT 610, HD 7750 or GT 640) should be able to handle everyday tasks like YouTube, word processing and web browsing easily with some room for casual gaming/video editing.
edit: Your computer and PSU should be able to keep up with budget video cards
