I need some advice on which graphics card is worth investing in. I'm running an Intel i7 950 Sandybridge on an Asus X58 Sabertooth. I currently have an ATi Radeon 5550, which is what I could afford when I built my new system, but I am doing a lot more GPU intensive work in After Effects and need to upgrade. I use 2x 21" monitors so need two outputs, preferably DVI My questions is this: Is it better to spend more on a single card with better capabilities or spend less on a card but get two and crosslink them? Based on suggestions from the various software manufacturers I have my eyes on the following cards: Radeon HD 6870, 7770, 7850, 7870, 7950, 7970 Does anyone have any experience of these cards, suggestions or tips? I do need to run my two monitors, so some of these cards wouldn't work individually for my setup and I would need two. I'm a bit lost on all the tech involved and want to spend my money wisely. Thanks in advance for all your help!
