Fine tunings before purchase

[jbgraver]

Hi guys,
I'm putting together my first DIY gaming build in the coming week, so I'd appreciate some opinions, primarily towards compatibility but also in regard to best value.

It'll be a casual gaming build on a budget (hard to convert the budget from DKK to $ or £, due to higher prices here in DK), but around 900$

Parts I need most help with: PSU and RAM! (and GPU)


Parts NOT needed: HDD, Optical drive (not needed), case, OS, monitor (have BenQ HD2420), mouse and keyboard.

No preferred websites - but don't waste your time on deals, I live in Denmark (where such deals seem very rare)

Parts Preferences: I'm sold on the I5-3570K CPU, but no preferences besides from that.

Overclocking: Yes, in time

SLI or Crossfire: Maybe in time (I'd like to have the option and headroom for it)


The build so far:

CPU: I5-3570K

mobo: Asus P8Z77-M Pro
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131833&Tpk=asus%20p8z77%20m%20pro

RAM: Corsair Vengeance DDR3 8GB 1600MHz CL9 2x4GB Kit
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145345

GPU: Radeon HD 7850 (perhaps Sapphire's 2GB OC?)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102986&Tpk=SAPPHIRE%207850

PSU: I don't know, perhaps Cosair's Gaming GS700 or Enthusiast 650

I'm kind of lost on this part!

I hope this give an Idea of the budget/performance I'm looking for!?


My concerns:
How much wattage is needed for the future aspect of CPU OC (no more than 4,5 maybe less + hyper 212 evo cooler then), dual crossfire 7850's, the rest of the system and say 4 fans?

The RAM, are they good (there are so many different names within Corsair and then color codes do they mean anything). For some reason the G. Skill are a bit more expensive in DK, but are they worth the extra cash?

Games I'll be playing range from Shogun 2, Guild wars 2 to Assassins Creed and a little Crysis and BF3 - So I guess I both decent GPU and CPU!?

Any thoughts and help is very much appreciated, thanks!

crossfire 7850 with an OC'd i5-3570K will not use more than 425-450 watts when under full stress; gaming will be less so the 650 watts is plenty.

i believe the colors in the corsair RAM are strictly for matching color scheme of the motherboard. honestly the only difference is the major brands of RAM are only noticeable when benchmarking; daily use will have little difference.

your system as is will have no problem playing the games you listed; 35- 60+ fps @ 1920x1080 depending on your settings, ultra/high or medium.

Great! Thank you for your advise, exactly what I wanted to hear ;-)

As there's not much room in the budget for improvements (read better GPU) I'll just have to see which settings it can pull when I get the PC put together - I'm sure it'll impress compared to my laptop!
