Alright, I have an HP 6719c desktop computer that was purchased from costco about a year and a half ago.
This is it. http://h20000.www2.hp.com/bizsuppor...portFAQ&prodSeriesId=5035348&prodTypeId=12454


I want to upgrade the power supply and graphics card so that I can play modern warfare 2, dayZ, left4dead1/2, FNV without the computer lurching and just plain quitting on me.

Would I be bottlenecking myself by just upgrading these?

These are the parts i was considering. If you know more or have a better idea, please share it.

I had a look at the computer you have and the parts you linked.

First of all bottlenecking is really something of a misnomer, unless you have a truly decrepid processor and are buying a top end graphics card or using crossfire/sli then it really isn't something you should excessively worry about. Sure you might get a few extra fps with a i5 3570K but it isn't a huge problem. As for your quad core Phenom it should be perfectly fine. A 7850 would be a great upgrade, it is what I am running now. It comes with a great games bundle right now, is a fairly cool and efficient card and has a great price/performance ratio right now. If you are technically minded, a lot of them also overclock like a beast (if you are inclined to explore OCing your card try and get a card with a custom cooler).

I'm not sure why you linked the 7750, it's not a bad card but I wouldn't recommend it as an upgrade unless you are gaming at resolutions of below 1080p (incidentally, pertinent question: what resolution will you be gaming at?).

As for the PSU I would be careful about that and put a good amount of research into it. Cheap and nasty PSUs have been the end of many a system. It's well worth spending a little extra to get a good brand PSU and they can often cross over multiple builds. Id suggest this :

Seasonic are generally considered one of the best if not the best PSU makes. Its 80 Plus Bronze rated so more efficient and has Japanese capacitors. As for the Raidmax I can't say it is a brand I have any experience with or have even heard of really. That's not to say it is a bad PSU necessarily just be aware.

 

I'd change my recommendation as well to that Corsair. Corsair are a great brand too and that is a really good deal for that PSU if you remember to send in the rebate. As for graphics card brands Gigabyte are a good brand as Cheddar said, I'd also suggest MSI. My own card is a Twin Frozr and it's never gave me a minute of trouble.

 

Thanks for all the great advice you guys.

I went ahead and chose to purchse the corsair PSU and an Asus 7850.

Although looking at it now I'm afraid I might have made a mistakewhen purchasing the Graphics card.

I was looking at the minimum requirements of some games and I don't think I will have enough VRAM to play them. Dayz's and Bioshock Infinite 's minimum requirements say that you need at least 512 MB of dedicated memory. Don't I only have 256? Was this a bad idea?

But then I think, why would they give you a free game for buying a card that couldn't run it?

 

It seems that you misread that - the card has 2 GB VRAM, and the 256-bit are how the VRAM is addressed, so you shouldn't have any problems with VRAM.

 

I had a feeling that My worries may have been unfounded. Thanks for confirming that.

My ignorance of things usually encourages me to second guess myself and sometimes I need to stop and reexamine the larger picture. Thanks man.
