I plan to upgrade some time early next year, I'm a 3D modeller so I will be using the rig for both gaming and for using demanding software.
I want to know if this is a worthy upgrade and whether I could use anything from the previous rig for the upgrade, all together the new rig will cost around £550 (~$890).
Looks decent, for gaming Intel is the better choice. A 660ti is also a good card, but don't get a reference card, spend more and get a good non-reference cooler and overclock it a bit, or just get a 670. Lastly, what PSU would it be, DO NOT SKIMP on the PSU.
Do you think there's anything in my current rig that I could use in my new rig?
Also should I get a 660ti or 670? I did some research and there's mixed feelings on which to get, I am on a budget but I'm willing to go up in price if its worth it.
Well, you could use your Hard Drive for sure, maybe grab an SSD if you want for booting, though that's kind of a waste of money if you're on a budget. Your GTX 460 would be a good dedicated PhysX card, though I'm not sure if your Mobo supports it, and the performance gains are minimal. Personally, I would reuse the hard drive and sell all the rest for as much as you can to pay for your new system.
I would recommend getting an Asus GTX 670 DirectCUII card, it's a good price for a beastly card, or if you'd like, wait until March or April and get the next generation of graphics cards from either company. Your call, good luck, feel free to ask any more questions.
A friend of mine put forward this build to me instead of the one I posted, can I get some feedback on it; whether it's better then the one I previously posted, power wise and value for money wise. ~£650(~$1000)
CPU - Intel Core i5 3550,1155, Ivy Bridge, Quad Core
MB - ASRock Z77 Extreme 4
GPU - 2GB MSI GTX 660 Ti Power Edition OC
RAM - 8GB (2x4GB) Corsair DDR3 XMS3
HDD - 1TB Seagate ST31000524AS Barracuda 7200.12, SATA 6Gb/s
PSU - 520W Antec Neo Eco 0-761345-285209
Case - Aerocool VS-9 Advance Gaming Mid-Tower Case
Performance would be relatively similar for both builds, Intel is the better choice for gaming, but if you are not going to be using a 670 or 680, might as well just stick with the FX-4300 and save a few bucks. It's really down to personal preference at this point, as performance won't vary too much between the two builds, at least not for the amount of money you are paying for the Intel vs. AMD build. That case is ugly though, maybe this? http://www.newegg.com/Product/Product.aspx?Item=N82E168...
