My current build is
Intel i5-750 (not OC'd)
ASUS P7P55 PRO Motherboard
2 x HD 5770 1gb DDR5
8gb Corsair XMS3 1600Mhz
128gb Crucial M4 SSD
2 x 1 TB Western Digital Green Caviar (raid)
750 watts Corsair TX750
I plan to upgrade the following components and keep the memory, HDD's, and PSU
ASUS P8Z68 V PRO/GEN 3 PCIe 3.0 ready (sandy/ivy bridge compatible for upgrade)
2 x 560ti 448 cores or 1 x HD 7970 (need your thoughts ^^, same price)
Is my current PSU enough to hold SLI'd 560ti 448 cores if i do decide to get it?
Should I get a P67 motherboard instead?
if Video Editing .... go for i7 -3930K... a lot better for doing Video stuff....
I agree with you on that but the price tag is a bit too high and also i need to change my memory as well if i change to LGA 2011 socket.
I'm trying to minimize the cost as much as possible. I wanted to wait for ivy bridge but it seems the release dates keep changing.
If it's slow then why not overclock? Simple as that, make things go faster!
It would, but an i7 will go faster still once you overclock that and factor in the hyper-threading.
If you were just gaming, I'd say upgrade the GPU only...I don't do video-editing so I don't know if the upgrade you're looking at would be worth the cost for the performance gain (others more knowledgeable than me can help here). However, I would have thought getting the single most powerful GPU you can would be a better bet...but bear in mind if you plan to go multi-GPU later, get a PSU now that will handle both cards. Also, AMD Crossfire is easier in the sense that you don't need a higher end mobo that supports it (like you need with SLI, thanks Nvidia...).
If you're not seriouse gamer .... and major I would put the money on the i7 -3930K first .... and upgrade the video card later...or buy a cheaper video card use first ~ $2xx... i7-3930K is ~ $300 More and MB is around $2xx something almost $50 more than the one you choose...and memory is cheap even 32GB 1600 is around $200...
Let's be clear here...a Sandybridge-E CPU is not recommendable for someone who is just gaming. It's an enthusiast part...highly expensive, and is the basis for a high-end, water-cooled rig (yes, it could be air-cooled, but they're not being aimed at a market who would consider air-cooling over water-cooling).
Let's be clear here...a Sandybridge-E CPU is not recommended for someone who is not seeking the highest-end parts in their system and is not looking to push their system to the very edge of what PCs can do today. It's an enthusiast part and as such it is highly expensive. Sandybridge-E does not offer extra performance over Sandybridge that justifies the extra cost for someone who wants a PC that will encode or game. For the OP, who's encoding, an i7-2600K or i7-2700K would be more than adequate. The i7-2920K is ~ 2x the cost, and again, the additional performance would not justify the expense.
