I have been reading posts on this site for a couple of days, all very helpful!! I need a new graphics card for my Dell Inspiron 620. The reason? XCom Enemy Unknown! I downloaded the demo, and the nostalgia was overwhelming, i need to buy this game!! The performance of the demo was not good, so I think a graphics card is a necessity, as well as RAM upgrade.
Here is the thread that is most similar to my query;
Dell is being extra cautious about straining the power supply (which they should be) and is recommending underpowered cards. It is likely that the PSU could handle a 6670 or a newer equivalent (7750, GTX 640/650) but its always better not to take risks.
Are you willing to consider a power supply and graphic card replacement? If so, you could get more power for £150. The rest of your system is pretty good, I see no reason not to invest in a more powerful card/better power supply.
Power supply is VERY easy to do, you just unplug the cables, remove it, replace it, and plug the cables in again.
I just checked, they're cheaper than i thought! But I'm guessing the more expensive the better, right? Reviews of the cheap 'Ace' PSUs are pretty disconcerting..... burning smells, going kaput in a week etc.... What are the good PSU manufacturers?
Looks like I'm going to increase my budget... lol
I think the best way to go about it is to find the most powerful low-end, or least powerful mid-range graphics card, and get a PSU to match. What would you recommend? I'll do some searching in the meantime...
Power supplies: You are looking for a higher efficiency unit (at or higher than 85%) in the 380w-500w range. 450w is enough to run ANY single card, 380w is enough for the newer mid-range cards you are looking at (but a little margin is always nice).
I can vouch for quality on Seasonic, Corsair, Antec, and most Silverstone, Be Quiet!, and PC Power models.
I would expect the newer architecture of the 7750 and 7770 to be more expensive, why is the 6870 the most expensive? I can imagine that 1Gb of DDR5 is better than 2Gb of DDR3, that explains the 6870 vs the 7750 OC price. But why is the 7770 OC cheaper than the older architecture of the 6870?
Is it the max memory bandwidth, which is almost double on the 6870? (plus higher compute power?)
Judging by the pricing alone, the 6870 seems the best choice/ most powerful, but I can't help but think that the 7000 series would be best?
When examining AMD cards, the first number is the generation, and the last three digits indicate its power (higher is better).
The 6870 is older, but was a more powerful card when new than the 7770. It's still a little bit more powerful. Its now discounted in price from its original entry point that was well above the 7770 range.
Its worth it to get the most power for the $$, but if you have two cards of the same power and different ages, always get the newer one.
Great, I think I'll go for the 6870, with a decent value power supply from the recommended list on AMD's website.
Another thread on here only recommended the 2Gb version on a multi- screen setup, makes sense, so the 6870 1Gb should do me fine
One more question before I take the plunge.....
Would there be any risk of bottle-necking on my system? I'm not au-fait with this, so any advice would be appreciated. I think my CPU is fairly decent, so it won't 'hold back' the graphics card will it?
