|---|---|---|
| XFX GeForce GTX 260 896MB | Sapphire Radeon HD 5770 1GB | ASUS Radeon HD 5770 VT 1GB |
| 87.8 | 71.15 | 80.4 |
First up, the average frame-rate produced by the three cards is more than acceptable. GeForce GTX 260 is a significantly older GPU that's still pretty quick, especially at the £125 price point.
The overclocked ASUS HD 5770 pulls an extra 13 per cent over the stock card here.
| Crysis - 1,920x1,200 4xAA (Enthusiast) | ||

| XFX GeForce GTX 260 896MB | Sapphire Radeon HD 5770 1GB | ASUS Radeon HD 5770 VT 1GB |
| 14.23 | 15.05 | 17.14 |
Crysis is just painful to play at the enthusiast setting, even with a 13 per-cent boost.
| Enemy Territory: QW - 1,920x1,200 4xAA 16xAF | ||
|---|---|---|
| XFX GeForce GTX 260 896MB | Sapphire Radeon HD 5770 1GB | ASUS Radeon HD 5770 VT 1GB |
| 76.87 | 66.73 | 76.17 |
Pulling back to parity with the GTX 260, the performance advantage over a basic card is 14 per cent.
| Far Cry 2 - 1,920x1,200 4xAA 16xAF | ||
|---|---|---|
| XFX GeForce GTX 260 896MB | Sapphire Radeon HD 5770 1GB | ASUS Radeon HD 5770 VT 1GB |
| 47.03 | 47.42 | 53.43 |
12.6 per cent here, and it's actually noticeable in the game.
| GRID Race Day 1,920x1,200 4xAA 0xAF | ||

|---|---|---|
| XFX GeForce GTX 260 896MB | Sapphire Radeon HD 5770 1GB | ASUS Radeon HD 5770 VT 1GB |
| 45 | 46 | 56 |
The biggest gain is in H.A.W.X, pushing average frame-rates up by almost 22 per cent.
Looking back at the numbers, prior to the HD 5770's launch, we expected the ASUS VT's performance to constitute a stock card's. Perhaps a Radeon HD 5790, once yields improve, may well be introduced and ship with a 1GHz core and, say, 5,500MHz memory?
Coming back to the state of play today, even with ASUS' SmartDoctor technology, there is no guarantee that all cards will hit a 1GHz core and 5.7GHz memory. What's more, there is a price to pay for extra voltage-driven performance...
