I want to upgrade for gaming and vids. To do this I believe I need a new PSU as well, so here goes:

The old stuff:

XPS 8500

Operating System Windows 8, 64-bit, English

Processors 3rd Generation Intel® Core™ i7-3770 processor (up to 3.90 GHz)

Memory 16GB Dual Channel DDR3 1600MHz - 4 DIMMs

Video Card AMD Radeon™ HD 7770 2GB GDDR5>>>>>>>>>>>>>>>>>>>>>>>>>>Remove and replace

Hard Drive 2TB 7200 RPM SATA Hard Drive + Intel® SRT 32GB SSD Cache>>>>>>>>>Possible removal and replacement

460W PSU>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Remove and replace

The new stuff:

MSI N670 PE 2GD5/OC GeForce GTX 670 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card

OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Sandybridge Core i3 i5 i7 and AMD Phenom OCZ ZX Series 850W Fully-Modular 80PLUS Gold High Performance Power Supply compatible with Intel Sandybridge Core i3 i5 i7

I'm not sure about keeping the HDD/SSD --I think the SSD is too small to hold the OS. If I have to replace it, this would be my setup:

Crucial V4 CT256V4SSD2BAA 2.5" 256GB SATA II MLC Internal Solid State Drive (SSD) with Easy Desktop Install Kit Crucial V4 CT256V4SSD2BAA 2.5" 256GB SATA II MLC Internal Solid State Drive (SSD) with Easy Desktop Install Kit Item

Western Digital Caviar Green WD30EZRX Hard Drive, 3.5" Form Factor, 3TB (3000GB) Capacity, 64MB Cache, SATA 6.0 Gb/s Interface

The OS would be a fresh install on the SSD.

The total cost for upgrade: $778.27

So, guys 'n' gals, what do you think? I'm not sure that I'm even in the right thread, but my aim IS to upgrade my video card. :pt1cable:

Err why dont you just keep the old hard drive and add an ssd? Also a 850w psu is overkill unless you plan on going SLI. A decent 500-600w psu is sufficient

Great! so just add an SSD. I said I was not sure, as it has been years since I built or tinkered with a 'puter. SLI is not my thing, so I will look into another PSU. Are my brand choices good ones?

Keep the current SSD as a cache for the HDD. No need to ditch either of them, even if you do decide to get a bigger SSD as a boot drive. I don't think I'd recommend a Crucial V4, it's pretty slow. Their m4 is faster, but still pretty affordable. The Samsung 840 is another good option; faster, but not with the same proven reliability (it's fairly new, but Samsung drives are usually great).

Your brand choices are fine in general. If you want to stay with OCZ for the PSU, I'd recommend the ZT series. Modular and good quality; the ModXStream line is borderline quality and the ZS line is full wired.
